Abstract
A rotatable seat for an occupant of a vehicle includes a generally horizontal seat portion, a generally upright back portion, and a structure for rotating the seat portion and/or back portion in reaction to an impact from the side of the vehicle to place the rotatable seat between the occupant and the intruding side of the vehicle.
Claims20
A rotatable seat for an occupant of a vehicle, comprising:
- a generally horizontal seat portion;
- a generally upright back portion;
- and
- means for rotating at least either one of said seat portion and said back portion about a vertical axis in reaction to an impact from a side of a vehicle to place said rotatable seat between the occupant and an intruding side of the vehicle.

A rotatable seat for an occupant of a vehicle, comprising:
- a generally horizontal seat portion;
- a generally upright back portion;
- means for rotating at least either one of said seat portion and said back portion in reaction to an impact from a side of the vehicle to place said rotatable seat between the occupant and an intruding side of the vehicle;
- said rotating means comprising pivotal means for allowing at least either one of said seat portion and said back portion to rotate laterally and impacting means for acting upon at least either one of said seat portion and said back portion in reaction to the intruding side of the vehicle;
- and
