Abstract
An adjustment apparatus for adjusting the position of a back pad or seat pad of a seat has an inner tube with a series of spaced openings for securing at one end to the back or seat pad, and an outer tube telescopically engaged over the inner tube and secured to a support frame of the seat. The outer tube has a pinning opening for alignment with a selected one of the openings in the inner tube. A lever is pivotally secured on a pivot bracket on the outer tube for rotation about a pivot axis with a first end portion of the lever projecting over the pinning hole, and a pinning button projecting from the first end portion towards the pinning hole. The lever is movable between an operative position in which the pinning button extends through the pinning hole and an aligned hole in the inner tube to secure the tubes together, and a retracted position in which the pinning button is spaced from the pinning hole. The width of the lever is greater than that of the pivot bracket, so that the lever extends over and completely covers the pivot bracket, avoiding potential pinch areas.
