Abstract
A sensor for sensing when a latch of a child safety seat is coupled to a seat assembly of a vehicle. The sensor may include a first housing member that is mounted to a seat frame of the vehicle. The sensor may also include a second housing member that can move relative to the first housing member. A sensor subassembly may sense the relative movement of the second housing member. The latch of the child safety seat can be snapped onto a ring of the second housing member and subsequently tightened to secure the child seat to the vehicle. Coupling the child seat to the ring moves the second housing member relative to the first housing member. This movement is sensed by the sensor which provides an output signal. The output signal can be processed to provide an indication to the vehicle driver that the child seat has been coupled to the seat, and/or disable an airbag and/or disable a seat movement device.
Description
- 1. Field of the Invention
- The subject matter disclosed generally relates to a sensor that can sense when a child safety seat has been coupled to a seat of a vehicle.
- 2. Background Information
- Infants and small children are typically placed within a child safety seat when traveling in a vehicle such as an automobile. The safety seat is strapped onto a seat with the seat belt of the vehicle.
- There has been enacted legislation that will require all vehicles to have a ring that extends from between the seat cushions of a seat assembly. Child safety seats will have a corresponding latch that will snap onto the ring and secure the safety seat to the seat assembly. The ring must have a relatively low profile so that occupants of the vehicle can sit on the seat without discomfort when the child safety seat is not in use. The low profile makes it difficult to determine whether the safety seat latch has been properly attached to the ring.
- There has been enacted legislation to require automobile manufacturers to disable the passive restraint system for occupants under a predetermined weight. Vehicles that comply with this legislation may have a weight sensor in the seat that senses the weight of the occupant and provides a feedback signal to the restraint system. Unfortunately, the new latch feature of the child safety seat may be tightened to create an improper reading of the occupant's weight. The additional tension force of the latch may increase the force sensed by the weight sensor so that the system mistakenly believes that an infant is an adult and remains enabled.
- It would be desirable to provide a system that would indicate when a latch of a child safety seat has been attached to a seat assembly of a vehicle.
- A sensor that can sense when a latch of a child safety seat has been coupled to a seat assembly.

FIG. 2 is a top front perspective view showing a sensor mounted to a seat frame; -
FIG. 3 is a schematic showing a sensor system; -
FIG. 4 is a top perspective view showing an embodiment of a sensor; -
FIG. 5 is top perspective view showing another embodiment of the sensor. - Disclosed is a sensor for sensing when a latch of a child safety seat is coupled to a seat assembly of a vehicle. The sensor may include a first housing member that is mounted to a seat frame of the vehicle. The sensor may also include a second housing member that can move relative to the first housing member. A sensor subassembly may sense the relative movement of the second housing member. The latch of the child safety seat can be snapped onto a ring of the second housing member and subsequently tightened to secure the child seat to the vehicle. Coupling the child seat to the ring moves the second housing member relative to the first housing member. This movement is sensed by the sensor which provides an output signal. The output signal can be processed to provide an indication to the vehicle driver that the child seat has been coupled to the seat, and/or disable an airbag and/or disable a seat movement device.
- Referring to the drawings more particularly by reference numbers,
FIG. 1 shows achild safety seat 10 coupled to aseat assembly 12. Theseat assembly 12 is typically part of a vehicle such as an automobile. Thechild safety seat 10 is typically configured to support an infant or small child, and rest on theseat cushions 14 of theseat 12. Thechild seat 10 includes a latch (not shown) that is coupled to theseat assembly 12. The tension of the latch may be tightened throughstrap 16. - As shown in
FIG. 2 , asensor 20 can be mounted to aseat frame 22 of the seat assembly. Thesensor 20 includes aring 24 that extends from between the seat cushions (not shown). The latch of the child safety seat can be snapped onto the ring to secure the child seat to theseat frame 22. - As shown in
FIG. 3 , thesensor 20 can be coupled to acontroller 30 or computer of the vehicle. Thesensor 20 can provide an input signal to thecontroller 30. Thecontroller 30 can then provide an output signal to adisplay 32. Thedisplay 32 provides an indication that the latch of the child safety seat has been properly secured to the seat assembly. Thedisplay 32 may provide a visual or audio indication. For example, the display may be a light lamp that is illuminated on the dashboard of the vehicle, or the indication may be a noise, or the cessation of a noise emitted by the vehicle. - The
controller 30 may also disable theair bag 34 adjacent to thechild seat 10. Theair bag 34 may be disabled when thecontroller 30 determines that the child latch has been properly secured to the seat assembly. Additionally, movement of the seat assembly may stretch or even break the child seat strap. Thecontroller 30 may also prevent movement of the seat when the latch is secured to the seat assembly. Seat movement may be inhibited by disabling the seat motor, engaging some type of mechanical latch, or other means. - The input signal from the
sensor 20 may be a signal that has two levels, one level to indicate that the latch has not been properly attached and another level that the child seat has been properly attached. Alternatively, the input signal may have an amplitude that varies with the latch force sensed by thesensor 20. For example, the voltage of the input signal may vary between 0-5V for a load range of 0-30 lbs. Thecontroller 30 can then determine whether the amplitude exceeds a threshold value and drive thedisplay 32, accordingly. Although acontroller 30 is shown and described, it is to be understood that thesensor 20 may provide the input signal directly to thedisplay 32. -
FIG. 4 shows an embodiment of asensor 20. Thesensor 20 may include afirst housing member 40 and asecond housing member 42. Thefirst housing member 40 may include aflange 44 with an opening 46. A fastener (not shown) can pass through theopening 46 to secure theflange 44 andfirst housing member 40 to a seat assembly (seeFIG. 2 ). Although aflange 44 andopening 46 are shown and described, it is to be understood that thesensor 20 may be attached to the seat assembly by other means. - The
second housing member 42 can move relative to thefirst housing member 40. Thesecond housing member 42 includes thering 24. Thering 24 can be formed with thesecond housing member 42 or attached to thehousing member 42, for example with a welding process. Thefirst housing member 40 may include stopsurfaces 48 that engageflanges 50 of thesecond housing member 42 to limit the travel of thesecond member 42. A portion of thesecond housing member 42 may reside in acavity 52 of thefirst housing member 40 to minimize the profile of thesensor 20. - The
sensor 20 further includes asensor subassembly 60 that senses movement of thesecond housing member 42. Thesubassembly 60 may include amagnet 62 and aHall Effect sensor 64. Located between themagnet 62 andHall Effect sensor 64 is anarmature 66. Thearmature 66 is mounted to a restrainingplate 68 that is attached to thesecond housing member 42. Movement of thesecond housing member 42 moves thearmature 66 and changes the magnetic field sensed by theHall Effect sensor 64. TheHall Effect sensor 64 provides an output signal onwires 70 that varies in accordance with movement of thearmature 66 andsecond member 42. Although a Hall Effect sensor is shown and described, it is to be understood that other types of sensors such as force or pressure sensors may be employed. - The
sensor 20 may include a biasingspring 72 that biases thesecond housing member 42 toward themagnet 62 andHall Effect sensor 64. Thespring 72 may be captured by awall 74 of thefirst housing member 40 and the restrainingplate 68. Thespring 72 may be centered aboutbutton 76. Thesensor subassembly 60 may be enclosed by acover 78 that is attached to thefirst housing member 40 throughfastener apertures 80. - In operation, the child seat latch is snapped onto the
ring 24. The latch is tightened which causes a force in the direction indicated by the arrow shown inFIG. 4 . The force moves thesecond housing member 42 andarmature 66. Movement of thearmature 66 is sensed by theHall Effect sensor 64. The output signal of theHall Effect sensor 64 varies as a function of the armature movement. The output signal can be processed by the controller (seeFIG. 3 .) to determine the latch force and whether the child seat latch has been attached to thering 24 andseat assembly 22. -
FIG. 5 shows another embodiment of asensor 20′. Instead of a Hall Effect sensor thissensor 20 includes aswitch 100 with amechanical button 102. Thebutton 102 is in contact with the restrainingplate 68. Movement of thesecond housing member 42 will move theplate 68 away from thebutton 102. Theswitch button 102 is internally biased so that thebutton 102 moves in an outward direction with theplate 68. Movement of thebutton 102 beyond some limit will cause theswitch 100 to provide an output signal. The output signal may represent that thesecond housing member 42 has traveled a certain distance, a distance that may indicate a proper attachment of the child seat latch to thering 24. The proper attachment force can be established by the spring force of thespring 72. - While certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of and not restrictive on the broad invention, and that this invention not be limited to the specific constructions and arrangements shown and described, since various other modifications may occur to those ordinarily skilled in the art.
