Abstract

An adjustable seat assembly for a vehicle comprises a pair of spaced-apart parallel support tubes which are mounted on the vehicle by means of a support bracket. Seat attachment means are provided and include a seat attachment plate and a pair of seat tubes which are slidably or telescopically engageable with the front ends of the tubes. A U-shaped torsion bar has two reversely-curved ends which are slidably or telescopically engageable with the rear ends of the seat tubes. Means are provided for bolting a seat to an attachment plate underlying the U-shaped end of the torsion bar so as to entrap the U-shaped end of the torsion bar therebetween. The seat, seat attachment means and torsion bar are slidable as a unit longitudinally with respect to the support tubes to desired positions. A springbiased notched locking bar is pivotably connected to the attachment means and any one of its notches can engage the edge of slot in the tube support bracket to lock the seat in a desired position.

Claims

1. A seat assembly for a vehicle comprising:

a seat;

support means comprising a support bracket and a pair of spaced apart tubular members rigidly mounted thereon, said support means adapted to be rigidly secured in a fixed position on said vehicle by said support bracket;

seat attachment means comprising a pair of seat attachment tubes connected by an intermediate portion, said pair of seat attachment tubes slidably engaged within said pair of tubular members;

an attachment plate pivotally mounted on said intermediate portion;

torsion bar means comprising a pair of end portions and a resilient intermediate portion, said pair of end portions engaged with the rear ends of said pair of attachment tubes of said seat attachment means; and

means for securing said attachment plate to said seat with said resilient portion of said torsion bar disposed between said seat and said attachment plate.

2. A seat assembly according to claim 1 wherein said intermediate resilient portion of said torsion bar means is reentrant and lies adjacent said tubular members of said support means.

3. A seat assembly according to claim 2 wherein said attachment plate is secured near the front of said seat and said seat rests on said intermediate portion of said torsion bar means.

4. A seat assembly according to claim 3 wherein said seat attachment means and said torsion bar means are movable as a unit and including releasable locking means for holding said unit in any one of a number of predetermined positions with respect to said support means.

5. A seat assembly according to claim 4 wherein said releasable locking means comprises a locking bar pivotably connected to said intermediate portion of said seat attachment means, said locking bar being provided with notches for engaging said support bracket of said support means, and biasing means for biasing said locking bar into engagement with said support bracket.

6. A seat assembly for a vehicle comprising:

a seat;

support means including at least one support means member adapted to be rigidly secured in fixed position on said vehicle;

seat attachment means including at least one seat attachment member slidably mounted on said support means member and further including an attachment plate pivotally connected to said seat attachment member;

torsion bar means connected to said seat attachment member and having a resiliently movable portion for resiliently supporting said seat; and

means for securing said seat to said attachment plate with said resilient portion of said torsion bar means being disposed between said seat and said attachment plate, said seat, said seat attachment means and said torsion bar means being movable as a unit to any one of predetermined positions with respect to said support means.

7. A seat assembly according to claim 6 including releasable locking means connected between said seat attachment means and said support means for maintaining said unit in any one of said predetermined positions.

8. A seat assembly according to claim 6 wherein said support means member and said seat attachment member are telescopically engaged with each other.

9. A seat assembly according to claim 8 wherein said support means member is tubular and wherein said seat attachment member extends into one end thereof.

10. A seat assembly for a vehicle comprising:

a seat;

support means including a pair of spaced apart support means members adapted to be rigidly secured in a fixed position on said vehicle;

seat attachment means comprising seat attachment members slidably engaged with said pair of support means members and further comprising a portion cOnnecting said seat attachment members, said seat attachment means further comprising an attachment plate pivotally connected to said connecting portion of said seat attachment means;

torsion bar means comprising two end portions connected to said seat attachment members and further comprising a resiliently movable portion; and

means for securing said attachment plate to said seat with said resiliently movable portion of said torsion bar means being disposed between said seat and said attachment plate.

11. A seat assembly according to claim 10 wherein said seat attachment means and said torsion bar means are movable as a unit and including releasable locking means connected between said support means and said seat attachment means for holding said unit in any one of a number of predetermined positions with respect to said support means.

12. A seat assembly according to claim 11 wherein said support means members are tubular members and wherein said seat attachment members extend therewithin.
