Abstract
To achieve further weight reduction and thinning of a seat structure. A laminated body obtained by sandwiching a planar membermade of cloth between planar membersandmade of synthetic resin to join them to one another via adhesive agent is used in a shell type frame member of the seat structure. Upon receipt of an impact, delamination is caused between the respective layers configuring the laminated body. Thereby, both the tensile stress and the Izod impact strength of the laminated body are lowered as compared with those of a homogeneous laminated body obtained by joining planer members made of homogeneous materials. That is, impact energy is converted to a force causing delamination between the planar members in the laminated body to be consumed, thereby absorbing the impact energy. Since the shell type frame member itself can absorb the impact, further weight reduction and thinning of the shell type frame member and a seat structure using the same can be achieved.
