摘要： An armrest assembly is self-adjusting as to height in response solely to the rotation of a connecting support lever to which an armrest is mounted. The adjustment mechanism includes a spring biased latch pawl engaging a ratchet wheel inside the support lever. The spring holds the pawl engaged to the ratchet when the support lever is rotated in one direction; the spring holds the ratchet wheel and pawl in disengagement when it is rotated in the other direction. The ratchet remains fixed relative to the movement of the armrest portion and the support lever. An adjustable cable running from the ratchet wheel through the support lever and into the armrest portion maintains the armrest portion in a horizontal position and provides adjustment above and below the horizontal.

摘要： A mechanical seat suspension inside a housing comprises parallel scissor arms and a support arm with a cam connected to suspension springs. The support arm, which carries the substantial majority of the seat load, has a height adjustment mechanism and a cam with two arcuate surfaces that define an imaginary pivot point. The use of the cam with the imaginary pivot point permits a more compact structure. Various embodiments of the support arm with a cam end and devices using the support arm are also disclosed. A shock absorber attached to the outside of the scissor arms dampens the stroke of the suspension springs connected to the cam. The ratio of the shock stroke travel to the vertical movement of the seat remains generally linear and constant, thus producing a more comfortable ride. Also included is a height adjustment mechanism on the support arm that interlocks with the cam by a pivoting pawl and biasing spring. The height of the seat is adjusted by the relative movement of the top portion of the housing to the lower portion. No external levers, triggers, or other structures are mecessary for seat adjustment. The tension in the suspension springs is adjustable to compensate for the weight of the rider. Another embodiment of the suspension includes a support assembly with two support arms that move relative to a cam that can be latched in five positions. Compression springs connected to the support assembly and disengaging arms with a disengaging roller permit a power assisted height adjustment.

摘要： An adjustable seat mounting mechanism is provided between a base part and a seat support part mounted for relative fore and aft movement. An adjustment mechanism is operatively associated between the base part and the seat support part for effecting adjustment between a locking mode preventing the fore and aft movement, an isolation mode permitting limited oscillatory movement between the base part and the seat part, and an unlocking mode to permit full fore and aft adjustment of the seat. A single manually manipulatable member is provided, movable with the seat, for effecting adjustment between the three modes.
