A vehicle seat with a backrest-side and/or a seat part-side base structure which comprises at least one movable sidepiece structure. At least the sidepiece structure of the base structure is made of at least one framework structure. The at least one sidepiece framework structure has flexurally elastic flanks and deflectable transverse braces which lie between the flanks and which are arranged on the flanks via elastic connecting element, whereby a force pulse that acts on the transverse braces of the at least one sidepiece framework structure from one direction via a flexurally elastic flank causes a compensating autoreactive deformation of the at least one sidepiece framework structure in the opposite direction at another point.

An adjustable vehicle seat includes a seat base having a seat surface and a backrest having a backrest surface. In the seat base and/or in the backrest, sensors are provided that detect forces, pressures and/or movements effected by a person sitting on the vehicle seat and consequently issue a signal. A control device is provided that detects the signals issued by the sensors and actuates actuators provided in the vehicle seat to adjust the seat base and/or backrest, or components thereof, in order to adjust the vehicle seat.

A vehicle seat is capable of being shifted to a walk-in state without side support parts or a tilt part hindering the seat back from folding forward. A seat includes a seat cushion, a seat back, and a leg rest part. The seat is provided with side support parts at left and right sides of an occupant, and a tilt part that moves a front portion of the seat cushion upward and downward. The seat is further provided with a detecting part that detects a state of the seat back, and a control unit that causes at least one of the side support parts and the tilt part to transit from a deployed state to a housed state when the detecting part detects that a forward turn of the seat back is started.

A vehicle seating assembly includes a seatback and a seat base. The seat base is operably coupled to the seatback. The seat base includes a first suspension assembly and a second suspension assembly. The first suspension assembly includes a seat pan assembly and a seat cushion assembly. The seat cushion assembly is positioned above the seat pan assembly. The second suspension assembly includes a plurality of independent thigh supports operably coupled to a forward portion of the seat pan.

A pad is adapted to set on a seat pan included in a vehicle seat. The pad includes a cushion on the seat pan and a cushion cover on the cushion.

A biological sensor is provided with at least two sensors for detecting vibrations, and is configured so that the at least two sensors form layers. One of the at least two sensors is a first sensor used to acquire biological information, and one is a second sensor used to remove noise. A first cushion material for reducing vibrations is disposed between the first sensor and the second sensor. The first cushion material is integrally laminated with the first sensor and the second sensor. This facilitates accurate detection of biological information.

A seating assembly having a seating assembly frame that includes a seat frame and a seatback frame. The seating assembly includes an extension member coupled to the seat frame and movable in response to an actuating force between an extended position relative to the seat frame and a compressed position relative to the seat frame and including an end fixedly coupled to the seat frame and an end coupled to an adjustment device disposed on the seat frame.

An occupant protection apparatus includes: a vehicle seat arranged in an inner space of a side wall of a vehicle; a side airbag device provided in the side wall or the vehicle seat and including a side airbag to be inflated and deployed between the side wall and the vehicle seat. The vehicle seat includes: a pressure-receiving portion to receive a load from an occupant seated on the vehicle seat; and a frame to support the pressure-receiving portion. The occupant protection apparatus further comprising an electronic control circuit configured to perform moving the pressure-receiving portion so that the occupant is pushed away from the side wall before the occupant comes into contact with the side airbag at an activation time when the side airbag device is activated by an impact acting on the side wall from an outside of the vehicle and the side airbag is inflated and deployed.

The time required to complete current-to-target state transitions of a plurality of movable portions constituting a seat is shortened. A seat unit 1 includes an occupant support portion S1, a plurality of movable mechanisms respectively moving a plurality of parts constituting the occupant support portion S1, and an ECU 40 controlling respective operations of the plurality of movable mechanisms. The ECU 40 causes each of the plurality of movable mechanisms to undergo a transition from a current state to a target state and the plurality of movable mechanisms have a first movable mechanism requiring a longest time for the transition. The ECU 40 causes the transitions of the plurality of movable mechanisms other than the first movable mechanism to be completed by completion of the transition of the first movable mechanism from the current state to the target state.

A seat adjustment system for a vehicle seat is provided. The seat adjustment system includes a seat body; at least one actuating unit, configured to adjust a support of the seat body; a sensing unit, configured to obtain and provide seat information and body shape data of a back of an occupant; and a control unit, configured to control the at least one actuating unit; wherein when one parameter of the seat body changes, the control unit makes a portion of the body shape data of the occupant in a pre-defined range via the at least one actuating unit.
