AUTOMOBILE SEAT.

1 Application filed August 2, 1926. Serial No. 126,698.

roads which cause a compression of the springs in the seat. Y Y

Automobile seats are ordinarily built with springs inclosed in the seat portion as well as in the back-rest cooperating therewith, both of these being inclosed and covered by upholstery, but, the seat portion and backrest are entirely independent of each other, and an uneven movement of the vehicle over the road may cause a compression or expansion of the springs in the seat without alfect ingtor without moving the back-rest, so that as the person riding on the seat is moved up or down by reason of that compression or expansion of the spring therein, his back will be "moved over the surface of the backrest, causing a decidedly unpleasant rubbing action between his back and such back-rest. This invention eliminates that unpleasant rubbing action by connecting the back-rest with the seat portion and mounting the seat portion uponsprings inclosed in the casing, so that such seat portion may slide up and down in the casing, and whenever such sliding movement occurs,- the back-rest Wlll move therewith without causing a change in relative positions of these parts.

Metal guide plates are provided on the edges of the-seat to direct the slidlng action thereof and these metal guides fit within the casing which also contains the springs for supporting the seat. The'back-rest may be hinged to-the seat in order that it may be let down in a lowered position to form a bed with the seat and back-rest.

Suitable connecting rods are also provided for connecting the back-rest with the seat and for holding it in its raised position when not used as a bed.

In the accompanying drawings:

Fig. 1 is a perspective view of tion partly in section; and

Fig. 2 is a detail perspective view of the same. a

The numeral 1 indicates the automobile body within which is arranged a casing 2, preferably of metal, althoughit might be of any other material, and WlllCh is provided with a transverse partition 3.- Aseat 4 is provided with a base plate Shaving sirable.

the invensuflicient resilient support for the back and downturned portions 6 at the outer. edges thereof, which downturned portions 6 terminate in outwardly extending lugs 7, and the plate 5 iscovered with suitable upholstery 8. Metal guide plates 9 are secured to the outer edges of the lugs 7 as clearly shown in Fig. 2, and these guide plates 9 are adapted to be interposed between the lugs 7 and the metal casing 2 in order to permit of a sliding action between the seat 4 and the casing 2. i

The back-rest 10 may be of any suitable form and is hinged to the seat 4 by means of hinges 11 which, as shown in Fig. 2, connect the back 10 with the plate 5 of the seat.

4. The purpose of hinging the back 10 to the seat 4 is to permit of its being lowered into a horizontal position to use the whole seat and back as a bed for reclining if de- In order to hold the back 10 in its normally raised position. asshown in Fig. 1, it is detachably or adj ustably connected with the seat 4 by means of the holder-bars 12,

at'the opposite ends thereof, which are connected with the back 10 in any suitable manner to provide for such adjustment and regulation.

The, back 10 is thus connected with the seat 4 to move therewith as the latter is slidable in the casing 2, and for the purpose of resiliently supporting the seat 4 above the casing 2, suitable springs 13 are interposed between the plate 5 and the partition 3, and similar but shorter springs 14 are interposed between the partition 3 and the lugs 7 Thesevsprings normally hold the seat and back in the positions shown in Fig. 1

but whenever the vehic e moves over an uneven place in the road, t springs are caused to expand and contract, sliding the seat 4 in the casing 2, such sliding action being guided and directed by the metal guide plates 9, and by reason of the connection between the seat 4 and the back 10 this back is also moved with the seat, in order to prevent the movement of one relative to the other.', The springs 13 and 14 provide a cluding a casing, a seat associated with said casing and having a bottom plate, said plate having downwardly extending and outward- 1y projecting lugs formed on the edges thereof, guide plates secured to the outer edges of the lugs for guiding the sliding movement eluding a casing, a seat associated with said casing and having a bottom plate. said plate having downwardly extending and outwardly projecting lugs formed on the edges thereof, guide plates secured to the outer edges of the lugs for guiding the sliding movement of the seat within the casing, springs mounted within the casing and engaging the plate and lugs for resiliently supporting the seat, a back pivotally secured to the seat to slide therewith relative to the casing, and means for adjustably holding said seat back in its raised position and to permit the same to be folded down in a substantially hori zontal position.

3. A device of the character described including a casing, a seat slidably mounted for substantially vertical movement in the casing, said seat having a bottom plate provided with downwardly extending and outwardly projecting lugs formed on the edges thereof, guide plates interposed between the outer edges of the lugs and casing and carried by the lugs for guiding the sliding movement of the seat, a back rest secured to the seat independently of the casing for vertical movement therewith, a partition mounted in the casing and supporting springs inmounted within the casing for resiliently supporting the seat. v

5. A device of the character described including a casing, a seat associatedv with the casing and having a bottom plate provided with downwardly extending and outwardly projecting lugs formed on the edges thereof. guide plates secured to the outer edges of the lugs for guiding the sliding movement of the seat within the casing, and springs engaging and supporting the plate and lugs for resiliently supporting the seat.

In testimony whereof I afliX my signature.

WILLIAM SHEETS.
