To all whom it may concern Be it known that l, Tonmsll lrntnn, a citiimprovement in auxiliary seats of a type .especlally useful 1n connection wlth automobiles and other vehicles, although it may be applied elsewhere if desired.

The object of the invention is to provide an improved chair or seat which can be folded and stored in small space when not in use, but which when erected, has four legs, which make it strong and dependable as an ordinary chair. I

The chair is so constructed that the two front legs and the two rear legs are rigid with each other, and when the chair is collapsed, these legs fold under the seat. A pack is provided which folds down upon the seat. When the chair is erected, the legs are locked in upright position.

In the accompanying drawings,

Figure 1 is a side elevation of the chair erected.

Fig. 2 is a similar View of the same folded.

Fig. 3 is a detail of one of the leg joints.

Fig. l is a detail showing the connection of the legs with the floor.

Referring specifically to the drawings, 1 indicates the seat, which sets between two hollow side frames or casings 2, to each of which the front leg 3 is pivoted by a bolt 1 to ears 5 depending from the frames. Near its upper end, the leg has a hole 6 to receive a locking pin 7 supported in a recess in the frame 2, the pin being pressed behind by a spring 8, confined by a screw plug 9. The leg has a lip 10, which stops against the frame 2, when the leg is in vertical position.

The rear leg unit 11, is pivoted at 12, to the under side of the seat frame, near the rear thereof, and swings forwardly under the seat, as indicated by the dotted line 13, the legs 11 being set close enough together to swing between the front legs. 1

The rear leg unit has an extension 14!: at its upper end, provided with a slot 15, this extension swinging within a cavity in the seat frame. A locking rod 16, at each side, is connected to the extension 14 by a pin 17', which works in the slot 15, and this rod 16 is also attached by a pin 18, to an car 19 on a locking plug 20. The pin 17 also connects the rod 16 to an arm 23 depending from the folding back 21, which is pivoted at 22 to the seat frame.

he front legs 3 are connected at their lower ends by a cross bar which is pivoted at 24:, at the middle line of the seat, to a foot frame 25, the toes of which extend through slots in runways 26 which are set in the door, and thetoes are provided with rollers 29, which travel back and forth in the runways or tracks. The foot piece also has a heel 28, adapted'to engage in a hole in the track member 26, as shown in Fig. 1, when the chair is'pulled out and set up.

In operation, by folding down the back 21, the rods 16 are pulled rearwardly, withdrawingthe plugs 20 from their locking position above the front legs 3. The rear legs can then be folded under the seat, and then the front legs similarlyfolded under the seat, as shown in Fig. 2, the pin 17 traveling in the slot 15, when the parts are folded, and the feet 25 swinging on the rollers 29 and through the slot in the track casing 26. Then the whole chair may be pushed along the tracks to stored position as under an automobile seat or the like. When the chair is to be erected, it is first pulled out, and then swung up on the front legs. The back is then swung up and the same action causes the rear legs to swing down to .a vertical position, and by means of the rods 16, the locking plugs 20are advanced to position above the front legs and lock said legs in erect position. The chair as a whole may be turned on the pivot 24 to face it in different directions if desired.
