Claims

[Scope of Claim for Utility Model Registration] (1) A hinge shaft is inserted through hinge brackets attached to the front end of a seat main frame fixed to the vehicle floor and the front end of a cushion frame arranged on the seat main frame, respectively. ,
A cargo seat that can be converted into a cargo bed by making it possible to flip the seat cushion forward and defining a space for loading cargo between the seat cushion and the seat back on the seat main frame. The hinge structure includes a biasing means disposed between the seat cushion and the seat main frame to bias the seat cushion in the seat back direction, and a biasing means that interferes with the biasing means when the seat cushion is flipped up, causing the biasing of the biasing means to be biased. A hinge structure for a seat used as a loading platform, characterized by comprising: a stopper means for temporarily holding a seat cushion in a raised position by regulating force; (2) The biasing means is a torsion spring wound around the hinge shaft, each end of the torsion spring is locked in a locking part provided on each hinge bracket, and the stopper means is attached to either hinge bracket. The cargo bed seat according to claim 1, which is formed from a projection provided on a torsion spring, and the projection is latched to an end of a torsion spring to temporarily hold the seat cushion in a raised position. Hinge structure. (3) The cam is inserted into and fixed to the hinge shaft, the hinge shaft is integrally rotatably connected to one hinge bracket, and the biasing means is a leaf spring fixed to the other hinge bracket. , the free end of the leaf spring comes into contact with the cam surface of the cam and applies a biasing force to the cam and one of the hinge brackets. Utility model registration claim 1, which is a locking portion that abuts and locks the surface and the free end of the leaf spring, and is provided on the cam surface and the free end, respectively, and these locking portions constitute a stopper means.
Hinge structure of the loading platform sheet described in section. (4) The scope of the utility model registration claim in which the locking portion on the side of the cam surface is a convex portion at the maximum displacement position, and the locking portion on the free end side is a concave portion into which the convex portion of the cam surface is locked. The hinge structure of the loading platform sheet according to item 3.
