ABSTRACT:
A cab side wall mounted seat support has a slide assembly, typically a bar and sleeve assembly, attached to the wall and coupled by an upper arm support to a seat socket. A lower arm has a peg which engages one of a series of holes in the wall for locking the seat in place. The slide assembly includes a rotation function allowing the socket to be raised to release the peg from the hole for seat adjustment. Alternatively, the upper arm support is hinged to permit such release. One embodiment uses a roller on the lower arm instead of the peg and a spring loaded locking pin in the slide assembly releasably holds the seat in place.
