Abstract: A vehicle seat comprises a controllable deformable material and control apparatus is provided for controlling the state of a controllable deformable material. The control apparatus is configured to generate a signal to cause a control element in proximity to the controllable deformable material to change the characteristic of the controllable deformable material and thereby change the state of the controllable deformable material. The controllable deformable material is controllable to change state from a first state to at least a second state and is controllable to change state from at least the second state to the first state, the controllable deformable material being more deformable per unit force in the second state than in the first state.

Abstract: A restraining device control system includes: a restraining device that is provided at a vehicle seat and that restrains an occupant seated in the vehicle seat; a surrounding environment detection unit that detects an environment surrounding a vehicle; and a control unit that increases a restraining force on the occupant by the restraining device in a case in which it has been predicted, from the surrounding environment of the vehicle, that vacillation of the vehicle while in an autonomous driving mode will exceed a threshold amount and that decreases the restraining force on the occupant by the restraining device in a case in which it has been predicted, from the surrounding environment of the vehicle, that the vehicle will maintain a state in which vacillation of the vehicle while in the autonomous driving mode is less than the threshold amount.

Abstract: Embodiments of the present invention may include a vehicle seat having a cushion pad, a surface member, and a rigid member.

The rigid member is provided inside the side support portion of the cushion pad. The rigid member is of higher rigidity than the cushion pad, and protrudes in the same direction in which the side support portion protrudes. The rigid member has an end portion contacting the surface member.

Abstract: [Problem] To provide a comfortable backrest chair. [Solution] A shape retaining material is formed to have radial cores 12 distributed and radially extending upward from a base plate adjacent a cut hole 4 to be fitted on a chair support frame, and a first and a second reinforcing cores 13 and 14 arranged adjacent the base plate of the radial cores 12. A core sheet is formed by attaching a first, a second and a third mesh sheets 9 to the shape retaining material. A chair sheet material is formed by attaching a first and a second buffer sheets 15 and 16 and an outer surface side buffer sheet 7 to the core sheet. A backrest portion of the chair sheet material is constructed to have a larger right and left width than the breadth of a seated person's shoulders, and when the load of the seated person is applied, right and left opposite ends of the backrest portion can be displaced in directions to approach each other due to elasticity of the core sheet.

Abstract: An arrangement in passenger vehicles, that diverts the impact energy in impacts away from the passengers to the remaining mass of the vehicle thereby protecting the passengers, and in the same arrangement provides utilitarian access to the vehicle, such utilitarian access making it possible to both install multi-element contoured surround seats for passengers and the driver, and also a safety device for head-on collision protection that obviates the need for conventional seat belts and front impact airbags. An indo-skeletal structural arrangement proposed for the vehicle, provides further benefits by targeting the strength of the vehicle to protect passengers while minimizing other massive elements in the vehicle.
