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. 1. A hinge structure for a cargo bed seat, characterized in that a biasing means for biasing the seat cushion in the seat back direction is disposed between the seat cushion and the seat main frame. (2) The carrier sheet according to claim 1, wherein the biasing means is a torsion spring that is wound around the hinge shaft and whose end is locked in a locking part formed on each hinge bracket. Hinge structure. (3) Practical use of providing play between the torsion spring locking part of each hinge bracket and the torsion spring end to provide a range in which the torsion spring does not bias the seat cushion at the beginning of the seat cushion's lifting stroke. A hinge structure for a loading platform sheet according to claim 2 of the patent registration claim.
