4 Claims.
This invention relates to vehicle seats and more particularly to an adjustable vehicle seat.
An'object of this invention is to provide in a seat structure means whereby the height of the seat, particularly the rear portion thereof may be adjusted at will, so that the seat may be made comfortable for different persons.
Another object of this invention is to provide an improved base structure which may be incorporated in a longitudinally adjustable base structure whereby' the conventional upholstered seat may be secured to a portion of the base structure and made vertically adjustable, particularly at the rear thereof.
The above and various other objects and advantages of this invention Will in part be described in, and in part be understood from the following detail description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:-
Figure 1 is a perspective view of a base structure for a seat constructed according to an embodiment of this invention, showing a portion of the conventional seat structure in section.
Figure 2 is a sectional view taken on the line 2 2 of Figure 1.
Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the numeral I designates generally a hollow base structure comprising a top plate Il, side Walls I2 and end walls I3, constituting dependent flanges secured to the top II. This base I0 is preferably of substantially rectangular configuration but, of course, it will be understood that the configuration of the base may be varied to suit the style of the seat with which this base I0 is combined.
In order to provide a means whereby the seat S may be vertically adjusted, particularly at the rear portion thereof, I have provided an adjustable frame, generally designated as I4, which is provided with offset forward end portions I5 engaging in slots I6 provided in the top I I adjacent the front or forward edge thereof. In the present instance, this frame member I4 is constructed of substantially U-shaped configuration with the parallel legs II thereof having the offset portions I5 and the bight or rear portion I8 of the frame member I4 is provided with a plurality of dependent or downwardly extending plates I9 provided with a plurality of spaced apart holes I9. The plates 20 extend through slots or openings 2| provided in the top II adjacent the rear portion thereof and preferably, the side walls or flanges I2 and the end walls or flanges I3 are of a height suicient to permit the plates I9 to extend substantially for their full length into the hollow base structure I0.
An elongated adjusting .bar or rod 22 is adapted to bedisposed in selected alined holes in the 5 plates I9, and the rod 22 will then engage the top II so as to prevent further downward movement'of the plates I9 and thus maintain the' rear portion of the frame member I 4in raised position. The rod 22 lis provided with a knob 23 at l0 one end whichis'adapted to extend partially through a hole 24 provided in a side member or bracing piece 25 which braces the back B, shown in dotted lines in Figure 2.
It will be understood that the base I 0 may have 15 associated therewith longitudinal adjusting means so as to adjust the base with respect to the floor of the vehicle to move the base forward or rearwardly of the pedals. Through the medium of the vertical adjusting means herein- 20 before described, the rear portion of the seat can be raised to the desired degree so as to raise the entire seat S, particularly at the rear thereof and thus make it possible for persons of varying heights to conveniently look over the forward 25 portion of the vehicle for driving or other purposes.
In the use of this adjustable means for a vehicle seat, the seat structure S may be attached by any suitable means to the frame member I4 and the base II may be fastened to the floor of the vehicle or secured to the usual longitudinal adjusting means for a seat. The offset portions I5 of the frame member I4 may be passed through the slots IB and in this manner the seat S is removably secured to the base I0 with the offset portions I5 acting as fulcrums or pivots for the seat S.
The rear portion of the seat S may be raised to the desired degree, the rod 22 being rst pulled out through the hole 24 in the side member 25. When the rear portion of the seat S has been raised to the desired degree, the rod 22 is slipped back through the hole 24 and through the alined holes 20 disposed closest to the top II. The rod 22 will then prevent further down movement of the rear portion of the frame I4 and likewise the rear portion of the seat S so that the height of the seat S may be adjusted to the convenience of the person driving the vehicle and this adjustment will also have the effect of throwing the body of the driver forwardly in addition to raising the body of the person so that the driver can more readily look over the dash or hood of the vehicle.
I claim:- 1. In a Vehicle seat structure, a hollow base,
having a pair of slots in the top thereof, a frame member on the top, offset slot engaging portions 5 carried by the frame, a plurality of apertured plates secured to the frame member on the side opposite from said slot engaging portions, and a frame adjusting bar engageable in selected alined openings in said plates and in rigid engagement with a portion of said base.
2. In a vehicle seat structure, a hollow base provided with a flat top, said top h-aving a pair of slots adjacent the forward portion thereof and a plurality of spaced apart openings adjacent the rear thereof, a frame member on the top, a pair of offset slot engaging portions carried by the frame at the forward edge portion thereof and providing means whereby the rear portion of the frame may be rocked, a plurality of apertured plates secured to the underside of the frame adjacent the rear thereof and loosely engaging in the openings in the top and a bar extending through selected alined openings in the plates and engaging the top to hol-d the rear portion of the frame in vertically adjusted position.
\ 3. A means for adjusting a seat comprising a hollow base having a top provided with slots adjacent the front portion thereof and also provided with a plurality of spaced apart openings adjacent the rear portion thereof, a frame member, slot engaging portions carried by the front portion of the frame member to rockably and detachably secure the frame member to the base, a plurality of dependent apertured plates secured to the frame member adjacent the rear thereof and loosely eng-aging in the openings in the top and a frame adjusting bar disposed in selected alined openings in the plates and engaging the top to hold the rear portion of the frame in vertically adjusted position.
4. A means for vertically adjusting a vehicle seat comprising a hollow base provided with a pair of openings adjacent the forward edge thereof and with -a plurality of alined spaced apart openings adjacent the rear thereof, a U- shaped frame member, offset portions carried by the free ends of the parallel legs of the U-shaped frame and engaging in said pair of openings in the forward portion of the top, a plurality of dependent apertured plates secured to the underside of the bight of the frame and loosely engaging in said spaced apart openings and a frame adjusting bar extending through selected alined openings in the plates and engageable with the top of the base to hold said plates against downward movement and thereby hold the rear portion of the frame in vertically adjusted position with respect to the forward end.
