Application April 29, 1931, Serial No. 533,656
The invention relates in general to a folding or tiltable chair or seat of general application wherever such articles are adapted for use. The invention particularly relates to a seat or chair designed for use as the front tiltable seat of an automotive vehicle or in any similar situations where it is desirable to provide a form of folding seat which can be moved quickly into an outofhe way position leaving an unobstructa clearance for entrance or egress from the vehicle or past the rear side of the tilted seat.
The primary object of the invention is to provide a. simplified form of folding seat which wi re secured in its normal position. against accidental folding or turning; which will be positively secured in such position and locked securely in position.
Another object of the invention is to provide form of securing latch which will be self ope 'ating to hold the seat in its normal position automatically as an incident of moving the seat into such position, and to provide a form of latch conrol for releasing the same which will be simple in construction and operation, which will be conveniently accessible along one of the exposed edges of the seat and which will be disposed so as to be unobtrusive and preferably concealed either by the chair itself or by the adjacent portion of the car structure.
Various other objects and advantages of the invention will be in part obvious from an inspection of the accompanying drawing and in part will be more fully set forth in the following particular description of one form of mechanism embodying the invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.
In the accompanying drawing:
Fig. 1 is a view in side elevation of a preferred embodiment of the invention shown in full lines in its normal, righted position and shown locked in such position, and in dotted lines shown in its tilted position released from its locked position;
Fig. 2 is an enlarged showing of the lower portion of the seat shown in Fig. 1 showing the position of the parts as the latch is about to engage its keeper; and
Fig. 3 is a view in end elevation of the latch and associated parts shown in the preceding figures and with parts broken away to show details of construction.
In the drawing and referring first to the showing in Fig. 1, there is disclosed a floor or other suitable support on which is positioned a chair as the structure shown is contype The chair is supported at its front edge on a hinge mounting 14 about which the chair as whole niav mal nos 11 as shown in full lines in l swung forwardly as shown in dotted on following conventional practices in this There is also illustrated a coiled spring which teds normally to either swing chair about the pivotal mounting wha. rel-eased f latch heeinafter described or which will tend to assist in lifting and. swinging the chair into its forward, inoperative position.
seat 12 is provided adjacent its rear 1 a foot 15 which engages the support if). 501 the purpose of holding th chair in its normal position and against the turi .g action of the sprin 15, there is provided a latch l? piv oted on fulcrum pin l8 mounted in bracket secured to the frame as of the chair and positioned to one side of seat 12. The latch has its lower end beveled as shown at 21 which hereled end is designed to project downwardly recess or opening 22 formed in the support or door board 10. The lower end of the latch is of the conventional shouldered construction with the shoulder 22 designed to engage under a keeper 23 secured to the upper side of the support 10. The latch is maintained in engagement with its keeper by a coiled spring 24, one end of which is secured to the latch and the other end see red to an anchor 25 fastened to the underside of the seat.
The upper end of the latch is formed into a handle 26 disposed below the level of the seat as shown in Fig. 1, and to one side thereof as shown in Fig. 3, and designed so as to be conveniently accessible either to the occupant of the seat so that the latch may be unlocked as the occupant leaves the seat, or in the case of the device being used on an automobile, the latch and particularly its handle is preferably so disposed as to be readily operated by a person standing outside of the car and reaching through the open door to the latch handle. In operation it will be understood that with the parts shown in the position illustrated in lull lines in Fig. 1, it is simply necessary to swing the latch into position against the action of the spring 24 to permit the latch to escape its keeper after which the rear end of the seat, or the back, may be lifted or pushed forwardly assisted in those cases where the turning spring 15 is utilized. As the chair is swung from the dotted line back into its normal position, the pointed end of the latch will slide down past the keeper as shown in Fig. 2, thus placing spring 24 under tension and When the parts are restored to the position shown in Figs. 1 and 3, spring 24 will react on the latch to return the same into the holding position shown in Fig. l with the shoulder 22 disposed beneath the keeper.
