A vehicle seat support comprising two rails extending in a longitudinal direction, a central module slidably mounted on the rails and suitable for supporting the vehicle seat, a footrest slidably mounted on the rails in front of the central module and suitable for receiving the feet of an occupant seated on the seat, a first actuation system able to cause the central module to slide along the rails, and a second actuation system able to cause the footrest to slide along the rails independently of the central module.

A seat control device includes a memory and a processor coupled to the memory. The processor is configured to, based on a selection by an occupant of a vehicle, select a video display area for displaying a video from among a plurality of video display areas provided at the vehicle, determine an adjustment amount corresponding to the determined video display area for a vehicle seat provided in the vehicle, and, via a modulation section, modulate a position and posture of the vehicle seat based on the determined adjustment amount of the vehicle seat.

A display unit in a motor vehicle presents information to a first user located in a personnel site. A frame carries the personnel site and a suspension system between the frame and the personnel site has at least one adjustable suspension characteristic. While the motor vehicle is being operated, a control system repeatedly determines a first gaze point of the first user on the display unit. Variations in a position for the first gaze point over time are analyzed; and in response thereto, the control system generates a first control signal to the suspension system so as to reduce a fluctuation of the position for the first gaze point, if a repositioning of the first gaze point is out of synchronization with a displacement of the display unit.

A roof airbag system includes a roof airbag, a lifting mechanism, a collision sensor, memory, and a processor coupled to the memory. The roof airbag is provided at a roof portion of a vehicle, receives a supply of gas from an inflator and deploys toward an upper body side of a vehicle occupant sitting on a vehicle seat. The lifting mechanism is provided at a seat cushion side of the vehicle seat and lifts a thigh area of the vehicle occupant. A collision sensor detects a collision of the vehicle. The processor is configured to, when a seat back of the vehicle seat is tilted more than a predetermined angle to the seat rear side and the collision sensor detects a collision of the vehicle, control the lifting mechanism to lift the thigh area of the vehicle occupant and control operation of the inflator to deploy the roof airbag.

A vehicle seat management system configured to adjust one or more seats based on occupant and/or vehicular data. In one aspect, the occupant and/or vehicular data may be sent to a remote device for calculation of a seat adjustment algorithm. In another aspect, the seat adjustment algorithm may be sent via wireless transmission. In one example, the wireless transmission may be 5G.
