Abstract
An adjustable seating apparatus for a recumbent stepper includes a seat base mounted to a carriage, which is mounted for longitudinal translation along a guide track. The seat base can be rotatable relative to the carriage. The seat base includes a first handle for releasing the carriage from an elongate positioning member to adjust the longitudinal position, and a second handle for releasing the seat base from a positioning plate to adjust the rotary position of the seat base relative to the carriage. When the seat base has been rotated from its nominal position, the carriage will generally be prevented from being released from the elongate positioning member.
Claims16
An adjustable seating apparatus comprising:
- a guide track having a longitudinal fore-and-aft centerline;
- an elongate positioning member mounted to the guide trak generally parallel to the fore-and-aft centerline;
- a carriage member mounted to the guide track via a tracked connection for longitudinal adjustment relative to the guide track;
- a seat base mounted to the carriage member via a rotatable connection for rotary adjustment of the seat base relative to the carriage member;
- wherein the seat base has at least a first longitudinal locked position, a longitudinal intermediate position, a second longitudinal locked position, a first rotary locked position, a rotary intermediate position, and a second rotary locked position;
- a first handle mounted to the seat base via a first pivotable connection;
- a release activator mounted to the first handle portion;
- a locking lever pivotally mounted to the carriage via a pivotable connection, the locking lever having a first locking tab at an end thereof;
- a plurality of recesses in the positioning member aligned longitudinally therealong;
- wherein the first handle and release activator are biased toward a non-activated position;
- wherein the locking lever is biased toward a first locked position with the locking tab portion received in one of the plurality of recesses in the positioning member when the seat base is in the first longitudinal locked position or the second longitudinal locked position;
- a second handle mounted to the seat base via a second pivotable connection;
- a second locking tab fixedly mounted to the second handle;
- a positioning plate mounted to the carriage member;
- a plurality of recesses aligned circumferentially about the positioning plate;
- and
- wherein the second handle and the second locking tab are biased toward a second non-activated position with the second locking tab received in one of the plurality of recesses when the seat base is in the first rotary locked position or the second rotary locked position.

- a seat back mounted to the seat base;
- an arm rest rotatably mounted to the seat back via a rotatable connection:
- a bushing mounted to the seat back, the busing having inner and outer chambers therein generally separated by flange portion therebetween;
- a shaft portion mounted to the armrest and extending at least partially through the bushing, the shaft portion having an inner portion and an outer portion, wherein the inner portion has a smaller diameter than the outer portion, and the inner portion extends through a hole in the flange portion so that the inner portion is received in the outer chamber;
- and
- a coil spring mounted to an inner end of the inner portion and disposed within the inner chamber and between the inner end and the flange portion so that the coil spring biases the shaft portion inwardly.
