A seat includes an elongate ground engageable support 11, an elongate stabilizer 12 pivotably connected at one end to one end of the support, a seat 10 secured relative to the stabilizer or the support adjacent to the one end thereof, and a lock for releasably locking the stabilizer in a first position in which it is substantially co-extensive with the support and in a second position in which it extends at an angle to the support and forward of the seat. The stabilizer includes, at a position removed from the seat, a leg abutment 20 for making contact with the front of a seated user's leg.

An ambulator which can be mated to a wheeled frame to form a wheelchair is rovided to enable a paraplegic to stand on the ambulator and be separated from the frame for maneuvering in confined spaces. The ambulator has power operated articulated linkage for raising the paraplegic out of and free of the frame to the standing position on the ambulator; the compact base of the ambulator containing a drive mechanism for moving the ambulator in any desired direction through controls conveniently located on an arm rest. When the ambulator is mated with the frame, the linkage is lowered to carry the paraplegic in the sitting position.

A single-legged chair comprising a support post and a seat mounted on the support post at a predetermined position thereof so as to constitute a leg portion by a lower part of the support post below the seat, the general plane of the seat lying at an angle of 70.degree. to 85.degree. with respect to the support post at least when the chair is in use. In use, the seat lies virtually horizontally as the leg portion stands on the ground or floor in an inclined posture.

A portable stool useful for hunting, spectator events, and other uses which can be supported by any generally vertical surface such as a tree, wall, post, etc. and the ground is disclosed. The stool can be easily and quickly converted from a use mode into a compact mode for easy carrying and storage and back to a use mode. The preferred stool has a primary support member, a secondary support member, preferably pivotly attached to said primary support member, having a fork on one end, and a seat. The seat can be padded and preferably locks onto either the primary support member or the secondary support member, or both, in the compact mode. The primary support member can also have projections for attaching to a rope or cable making the stool also useful as a handle to pull or drag a heavy object such as large game.

A reclining seat back assembly for a wheelchair includes a frame member having a pair of side posts pivotally connected to the wheelchair chassis. Each side post has a rearwardly extending handle at its upper end. A pair of extendable struts each include a hollow outer strut member pivotally connected to the chassis and an inner strut member pivotally connected to one of the side posts and received in the outer strut member. The struts contract as the seat back is pivoted toward a reclined position and extend as the seat back is pivoted toward an upright position. Mounted on each outer strut member is a locking mechanism that includes an engaging member having a first engaging surface with a profile complementary to a second engaging surface on the lower end of the inner strut member. A spring biases each engaging member into engagement with its respective inner strut member. The engaging members are released from the inner strut members by actuating levers mounted on the side posts immediately beneath the handles. The actuating levers are connected to the engaging members by Bowden cable assemblies. In addition, the seat back is urged toward the upright position by a pair of spring-loaded link assemblies each having a lower end pivotally connected to the wheelchair chassis and an upper end pivotally connected to a lever arm extending from the lower end of a side post.
