Position memory for automatically adjustable seat assemblies
First Claim
1. A position memory for a seat assembly which includes a seat having a bracket member movable therewith, a seatback having a brace hingedly connected to said bracket member so that said seatback is tiltable with respect to said seat, and drive means for driving said seatback for swinging movement thereof relative to said seat, said position memory comprising:
- a rotary wheel member freely rotatably mounted on said brace and having a recess formed at the periphery thereof;
a pivotal member fastened to said brace and frictionally engageable with said wheel member for rotation of the rotary wheel member together with the tilting movement of said seatback;
means for pivoting said pivotal member for releasing the same from the frictional engagement with the rotary wheel member;
means for providing said rotary wheel member with an angular rest position under a condition wherein said pivotal member is released from said rotary wheel member; and
a toggle switch mounted on said bracket member and having an operation lever in constant engagement with the periphery of said rotary wheel member, said operation lever being engaged with said recess of said wheel member when said wheel member assumes said angular rest postion, thereby to change an ON condition of the switch to an OFF condition and vice versa.

Abstract
A rotary wheel with a peripheral recess rotates with the adjusting movement of a motor-driven, adjustably movable seat. A manual lever is operable to freely rotate the wheel relative to the seat to an angular rest position, where a contact element of a memory switch engages in the recess of the wheel. When the seat moves back to the initial position after an adjusting movement, the contact element snaps into the recess to open the switch stopping the motor so that the seat automatically resumes the initial position.
