However, in the rear seat 1 configured as described above, for example, when the vehicle is suddenly stopped, the load loaded on the luggage floor 9 slides forward and the seat back 3A, When an impact is given to the 3B, the center hinge bracket 5 may not be able to withstand the impact. When the strength of the hinge 5 is increased, the impact on the floor 9 and the mounting portion of the rear seat back frame is increased. Therefore, if measures are taken to increase the rigidity of the members around the hinge bracket 5, the weight increases, and the vehicle weight is reduced. There was a problem going backwards. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. By adding a cushioning member to this center hinge bracket, it is possible to cushion an impact force from the rear against the seat back, and to provide a center hinge bracket. An object of the present invention is to provide an energy absorbing structure of a hinge bracket of a rear seat back in a vehicle in which surrounding members can be configured in the same manner as in the related art and an increase in vehicle weight can be reduced.

SUMMARY OF THE INVENTION In order to solve the above-mentioned technical problem, the present invention is directed to a center hinge mounted between left and right seat backs in a hinge bracket for a seat back of a semi-separable seat of a vehicle. The bracket includes a lower hinge to which a luggage floor between left and right seat backs is attached, and a pair of upper hinges that are pivotally connected to upper and lower portions of the lower hinge via left and right hinge pins, and a connecting portion formed on the lower hinge includes: A buffer member is provided at a predetermined position on the luggage floor so as to be attached obliquely in the form of a holding member. The second invention provides a configuration in which a bent portion is provided between a connection portion and an attachment portion of the buffer member. It was that. Therefore, when the luggage loaded on the luggage floor 9 slides forward due to the sudden stop of the vehicle and collides with the seat back of the rear seat, and when an impact force is applied, most of the impact force is applied to the center hinge bracket. When the support piece of the lower hinge is deformed forward, the shock force due to the collision of the load can be absorbed by the extension deformation of the buffer portion of the buffer member connected to the connection portion of the support piece, so that the impact force of the load can be reduced. It can buffer and respect vehicle legal regulations. Further, since the center hinge bracket is attached to the luggage floor side by the attachment piece of the lower hinge and the attachment portion of the cushioning member, the impact force acting on the center hinge bracket can be widely dispersed. Since it is not necessary to increase the strength of the portion, an increase in vehicle weight can be minimized.
