A compact and modular armrest having a frame with a pair of spaced apart downturned sidewalls each possessing a slot for capturing a portion of the thumbwheel that receives a height adjuster bolt having one end threaded into a nut anchored to a top wall web interconnecting the sidewalls of the frame and a head at its other end rotatively coupled to the thumbwheel with the bolt head bearing against the free end of a post attached to a bracket pivotally mounting the armrest to a vehicle seat. A retainer ring is secured to the bolt adjacent the head for keeping the thumbwheel and bolt captive to the frame. The ring also limits how far the thumbwheel can slide axially along the bolt head which also limits armrest height adjustment in one direction when the bolt is rotated in one direction. Height adjustment in the opposite direction can be limited by the ring bearing against the anchor nut when the bolt is rotated in the opposite direction. Preferably, height adjustment in the opposite direction is limited by an unthreaded portion of the bolt stem stopping against the threads of the anchor nut. A pad covering the frame also lines at least a portion of each slot for contacting the thumbwheel to dampen vibration and oppose random thumbwheel rotation. During operation, the thumbwheel is manually grasped between the thumb and forefinger of a seat occupant and rotated thereby rotating the bolt to raise or lower the armrest depending upon the direction of thumbwheel and bolt rotation.

Modular height adjustable vehicle seat armrest

A seat including: (A) a shell including a front surface, the front surface of the shell including a channel formed in the shell, the channel including an inner wall and an outer wall and having a shape; (B) a cushion including a rear surface, the rear surface of the cushion including a ridge extending rearwardly from the cushion, the ridge (1) having a shape which compliments the shape of the channel and (2) extending into the channel; and (C) mechanical fasteners extending through the outer wall of the channel, though the ridge and into the inner wall of the channel so as to retain the cushion on the shell. The mechanical fasteners do not extend all the way through the inner wall.

Seat having retained cushion

A backrest recliner mechanism for a vehicle seat or the like includes a connector and a locking mechanism which both pivot about the same line. The backrest recliner mechanism also utilizes the energy of the backrest biasing spring to aid in the return of the locking mechanism from a disengaged to engaged position. The mechanism is actuated by a handle which minimizes the forces required to unlatch the locking mechanism. The backrest recliner mechanism is designed so as to incorporate a minimum number of parts and also to be easily and quickly assembled with minimal modification of the seat shell.

Backrest recliner mechanism

A seat suspension having a stationary support that can be mounted on a vehicle. An intermediate frame is mounted on the stationary support for vertical sliding movement relative thereto by a spring suspension. A seat support frame is mounted on the intermediate frame for upward or downward movement relative thereto. A ratchet assembly interconnects the seat support frame and the intermediate frame and includes ratchet members on one of the frames and a pawl member on the other of the frames. A pawl release, including a biasing spring and a pawl actuating member, is provided to allow the support frame to be moved from the lower to any intermediate upper position and create an impulse at each position without need to activate said activating member. The activating member is operative to selectively move the pawl to a nonengagement position.

Seat suspension with quick height adjustment

A pivotable seat assembly for a mobile vehicle that allows the seat to be adjusted in fore or aft directions, pivoted to a position facing either of the directions, and then releasably latched against pivoting. The seat assembly includes a vertical support shaft member securable to the vehicle with a freestanding end having a primary abutment thereon; a rotatable support frame member having a top portion with the support frame member being rotatably mounted on the support shaft member so that the primary abutment projects beyond the top portion; a carriage for supporting the seat on the rotatable support frame member for sliding movement to a limit position; a latch assembly for selectively preventing rotation of the rotatable support frame member operatively connected between the support shaft and the rotatable support frame including, a fixed latch secured to one of the members, a shiftable latch mounted on the other member for movement into and out of engagement with the fixed latch, and a biasing spring for normally biasing the shiftable latch into engagement; a primary stop mounted on the carriage for movement therewith in the fore and aft directions and contactable with the primary abutment to define the carriage limit position; and a latch actuator mounted on the carriage for movement therewith into contact with the shiftable latch to move it out of engagement with the fixed latch and permit pivoting of the seat when the primary stop is in contact with the primary abutment to limit the amount of stress applied to the shiftable latch and the slidable carriage.
