Abstract
Abstract A seat (10) especially adapted for use by a mechanic includes a frame (11) which carries a seat cushion (21) and a lower tray (22). A tray frame (35) removably carries an upper tray (30) and is pivotally attached to the frame (11) by a pivot assembly (40). The pivot assembly (40) includes a hollow rod (41) attached to the tray frame (35). A coil spring (42) which carries pivot pins (43, 44) is slidably received in the rod (41). The pins (43, 44) engage the frame (11) so that the tray frame (45) and the upper tray (22) carried thereby are pivotal from a first position generally under the seat cushion (21) to a second position at least partially out from under the seat cushion (21) for ready access to items carried by the upper tray (22). The frame (35) may be maintained in the first position by a fastener (45) carried by the frame (35) and engageable with the frame (11).
