Abstract

A vehicle seat includes a pelvis movement suppression member, a moving mechanism, a control section and an energy-absorbing mechanism. The pelvis movement suppression member is disposed at a seat upper side of a seat front side of a seat cushion, extends in a seat width direction, and is movable in a seat front-rear direction relative to a frame of the seat cushion. The moving mechanism moves thepelvis movement suppression member from an initial position to a restraining position at a seat rear side relative to the initial position. When a collision is detected or predicted, the control section activates the moving mechanism and moves the pelvis movement suppression member to the restraining position.

Description

technical field [0001] The present disclosure relates to a vehicle seat. Background technique [0002] Japanese Patent Application Laid-Open No. 2002-370569 discloses a vehicle seat in which a slip-out preventing rod is provided as a waist movement suppressing member at a lower portion of a seat cushion. JP-A-2002-240608 and JP-A-2001-146127 disclose a vehicle seat in which a receiving member movable only in an up-down direction is provided inside a seat cushion. [0003] Japanese Patent Application Laid-Open No. 2002-370569 has a structure in which, when a vehicle collides, a slip-out prevention lever is moved upward by a power generating device to push up a seat cushion pad to suppress a submerged phenomenon. Japanese Patent Laid-Open No. 2002-240608 and Japanese Patent Laid-Open No. 2001-146127 are configured to prevent the receiving member from falling to suppress the occupant from moving forward of the seat when the occupant tries to move forward of the seat during a v...
