Abstract

The automobile seat assembly is provided with a seat swingably mounted on the spaced longitudinal brackets. An assembly mounted on one of the brackets and adapted for adjusting the seat position includes a latch member pivoted to the seat and a detent fixed to the bracket. The latch member is provided with notches for engagement with the fixed detent and operatively connected to a manual handle lever. When the manual handle lever is operated, the latch member may be moved into and out of engagement with the fixed detent and rotated on the bracket so as to adjust the height of the seat position.

Claims

1. In an automobile seat assembly having a set swingably mounted on longitudinally extending brackets which are secured to an automobile floor in spaced relation with each other,

an adjustable seat-supporting assembly mounted on said brackets, comprising:

a shaft mounted at each end thereof on said brackets,

guide means for providing fore and aft movement of said shaft,

a latch member fixedly secured to said shaft adjacent one of said brackets, said member including notch means thereon, and said seat being operatively connected to said latch member for movement therewith,

detent means fixedly secured to said one of said brackets and positioned for selectable engagement by said notch means;

a manual lever mounted on said one of said brackets for pivotal movement between unactuated and actuated positions,

cam means on said lever cooperating with said guide means for moving said shaft with the latch member secured thereto;

wherein the pivotal movement of said lever disengages and engages said notch means with said detent means; and

resilient means interconnecting said lever and said one bracket for urging said lever toward the unactuated position.

2. An assembly as claimed in claim 1 wherein said guide means comprises a horizontally elongated hole and said cam means comprises an arcuate elongated hole, said shaft being movably fitted within said elongated holes.

3. An assembly as claimed in claim 1 wherein a link member is pivotally mounted at its one end on said seat and at its other end on said latch member, to thereby interconnect said seat and said latch member.

4. An assembly as claimed in claim 1 wherein said detent means is a pin projecting from said one bracket.

5. An assembly as claimed in claim 1 wherein said means for urging said lever comprises a helical retracting spring provided between said manual lever and said one bracket.

6. An assembly as claimed in claim 3 wherein said link member is mounted on said latch member between said detent means and said shaft.

7. An assembly as claimed in claim 3 wherein said link member is mounted on said latch member at the opposite side of said shaft with respect to said detent means.

8. An assembly as claimed in claim 3 further comprising an additional bracket for securing said seat thereon, one end of said additional bracket being pivoted on said one bracket while the other end thereof is pivoted on said link member.

9. An assembly as claimed in claim 1 wherein said guide means comprises a link plate pivotally mounted at one end thereof on said one bracket and at the other end thereof on said shaft.

10. An assembly as claimed in claim 1 wherein a bracket plate provided with an elongated slot is secured to said seat, and a pin pivoted on said latch member is movably received within said elongated slot for interconnecting said seat and said latch member.

11. An assembly as claimed in claim 1 wherein said detent means is a plate provided with finger portions engageable with said notch means.
