Abstract

PURPOSE: To make a whole structure lightweight for ensuring the effective telescopic operation of a stand and simplify a structure by causing a seat tip-up operation by a telescopic and moving body. CONSTITUTION: A tip-up state holding mechanism 20 is provided with a lock member 23 on a travel seat at each stage, so that the base end of the member 23 is journalled to an operation shaft 12 rotatably laid laterally in parallel with a support shaft 11, with the free end kept in contact with the lower rear face of an erect support shaft 15 in a resiliently pressed state. Also, a tip-up operation mechanism 21 has telescopic operation bodies 28a and 28b laid laterally, and a cam plate 33 is rotated under the linear motions of the bodies 28a and 28b, thereby applying torque to the support shaft 11 in a direction for erecting the support shaft 15. Furthermore, a releasing mechanism 22 turns an action shaft 12 in a direction for releasing the contact state of the support shaft 15 and the lock member 23 against the resilient pressing force of the lock member 23, in conjunction with the travel seat under a retreating motion. According to this construction, the whole of a structure can be made lightweight so as to be effective for the telescopic operation of the seat and the structure can be as well simplified.
