A wheelchair seat back assembly comprising a seat back and mounting hardware for mounting the wheelchair seat back in relation to wheelchair seat posts, the mounting hardware comprising a mounting pin configured to be mounted in relation to one of the wheelchair seat posts or the seat back, and a pin receiver configured to be mounted in relation to the other one of the wheelchair seat posts or the seat back, the mounting pin being structured to be received by the pin receiver to mount the seat back in relation to the wheelchair seat posts, wherein the mounting pin is tapered and the pin receiver is tapered, thereby enabling the tapered shape of the mounting pin to cooperate with the tapered shape of the pin receiver to form a firm contact between the mounting pin and the pin receiver.
A wheelchair seat back assembly comprising a seat back and mounting hardware for mounting the wheelchair seat back in relation to wheelchair seat posts, the mounting hardware comprising a mounting pin configured to be mounted in relation to one of the wheelchair seat posts or the seat back, and a pin receiver configured to be mounted in relation to the other one of the wheelchair seat posts or the seat back, the mounting pin being structured to be received by the pin receiver to mount the seat back in relation to the wheelchair seat posts, wherein the mounting pin and the pin receiver are conically shaped.
A wheelchair seat back assembly comprising a seat back and mounting hardware for mounting the wheelchair seat back in relation to wheelchair seat posts, the mounting hardware comprising a mounting pin configured to be mounted in relation to one of the wheelchair seat posts or the seat back and a pin receiver configured to be mounted in relation to the other one of the wheelchair seat posts or the seat back, the mounting pin being structured to be received by the pin receiver to mount the seat back in relation to the wheelchair seat posts, the mounting hardware further including a pivotally mounted locking lever configured to be pivoted between a locked position, in which the pin is locked in the pin receiver, and an unlocked position, in which the pin can be removed from the pin receiver, and wherein the locking lever, when pivoted to the unlocked position, is positioned in a relation with the mounting pin so that removal of the mounting pin from the pin receiver results in a pivoting of the locking lever to the locked position, and wherein when the locking lever is in the locked position, the wheelchair seat back can be re-mounted onto the wheelchair and locked in place by inserting the pin into the pin receiver, without requiring additional adjustment of the locking lever to achieve the locked position, and further wherein the mounting pin is tapered and the pin receiver is tapered, thereby enabling the tapered shape of the mounting pin to cooperate with the tapered shape of the pin receiver to form a firm contact between the mounting pin and the pin receiver.
