Seat structure for vehicle

摘要

A seat structure for a vehicle has a deformation suppressant on at least one of a beam and an other region against deformation of the beam when a downward load acts on a front portion of the seat cushion upon for example vehicular collision or abrupt braking so that rigidity of the seat cushion can be enhanced with no reinforcement such as increase in diameter and/or thickness of the beam and/or a seat cushion frame, making the beam and/or the frame double-walled and/or use of high-strength material for the beam and/or the frame.
