A vehicle includes: a vehicle body frame; a drive unit provided on the vehicle body frame and movable on a floor surface; a seat disposed above the vehicle body frame to support buttocks of a user; a lift unit provided between the vehicle body frame and the seat to raise and lower the seat between a low position and a high position; and an operation device provided on at least one of a left side portion and a right side portion of the seat. The operation device includes an operation panel having an operation surface that faces upward, a lever extending upward and forward from a rear portion of the operation panel, and multiple operation members provided on the operation surface. At least one of the multiple operation members is disposed in a position overlapping with the lever as seen from above.

An occupant protection device for a vehicle includes a collision predictor, a main airbag, a seat, a sub-airbag, and a deployment controller. The collision predictor is configured to predict a collision of the vehicle. The main airbag is configured to deploy toward an occupant from a front of the vehicle when a collision of the vehicle is predicted by the collision predictor. The seat allows the occupant to be seated, and is movable in a front-back direction of the vehicle. The sub-airbag is accommodated in an upper part of the seat, and configured to deploy downward from above the occupant. The deployment controller is configured to, when a collision of the vehicle is predicted by the collision predictor, cause the sub-airbag to deploy from the upper part of the seat and subsequently cause the main airbag to deploy.

A multidirectional control apparatus for a vehicular seat is provided to perform anteroposterior tilting, lateral tilting, control of height and tilting in other directions in consideration of the body size of a passenger and the traveling environment. The multidirectional control apparatus improves passenger comfort by tilting the seat in a lateral direction when entering or exiting a vehicle, prevents the passenger from leaning to one side by tilting the seat in a lateral direction during turning of the vehicle, and offers a safety function of protecting the passenger by inclining the seat in the direction of a collision in the event of a collision of the vehicle.

A space management system for managing an environment of a shared space that is arranged inside a mobile body and can be used jointly by a first occupant and a second occupant comprises a control mode determining unit configured to determine a control mode serving as a control target of an adjusting unit configured to adjust the environment of the shared space. The control mode determining unit is configured to determine enabling or disabling of an independent control mode for independently adjusting an environment of a first subspace, which is a part of the shared space, where the first occupant is present and an environment of a second subspace, which is a part of the shared space, where the second occupant is present.

An apparatus and a method for supporting safety of a driver are provided. The apparatus for supporting the safety of the driver includes a sensor to sense collision of an electric vehicle, a voltage converter to convert down a high voltage of a high voltage battery, which is provided in the electric vehicle, to a low voltage and to supply the low voltage to a safety device, and a controller to activate the voltage converter in the state that power is not supplied to the safety device provided in the electric vehicle due to the collision, such that the driver is supported to be escaped from the electric vehicle while preparing for a secondary collision with the following vehicle, in the state that power is not supplied to various safety devices provided in the electric vehicle due to a car collision accident.

A vehicle occupant restraint device for the protection of a vehicle occupant in a vehicle seat comprises plural restraining elements and a controller. The controller differentiates between a first situation in which the vehicle seat is in a position within the range of a standard position, and a second situation in which the vehicle seat with the vehicle occupant is in a position beyond the standard position. When the first situation is given, the controller activates a tensioning unit for tensioning a seat belt of the second restraining element and an airbag of the first restraining element. When the second situation is given, a third restraining element integrated in the vehicle seat and/or operatively connected with the vehicle seat can be activated and/or connected by the controller so that the vehicle seat is moved initially via the third restraining element to a position within the range of the standard position.
