Abstract: A vehicle seat comprising a base, intended to be connected to the floor of the vehicle, a seating portion frame, hinged to the base so as to pivot about a transverse axis of the seat, a backrest hinged to the base so as to pivot about the transverse axis of the seat, hinge means connecting the seating portion frame to the backrest, configured so that the pivoting of the backrest relative to the base about the transverse axis causes the pivoting of the seating portion frame relative to the base about the transverse axis. The hinge means are also configured so as to connect the seating portion frame to the floor in order to move the front edge of the seating portion frame closer to or further away from the floor, the rear edge remaining fixed relative to the base.

Abstract: A vehicle seat height adjuster is configured to allow for a vertically oriented motor and spindle system. A ring-shaped lift plate allows the motor and spindles to pass through the lift plate, thereby allowing the lift plate to travel closer to the vehicle floor while eliminating the need for levered mechanical armature systems and complex transmission systems that convert motor rotation about a horizontal axis to vertical seat movement. The vehicle seat adjuster also offers pure vertical movement in the direction of the motor axis and has a relatively small footprint due in part to most of the components being located within a perimeter of the lift plate when retracted.

Abstract: An occupant support may include a seat bottom and a seat back coupled to the seat bottom. In some embodiments, a leg support is coupled to the seat bottom and configured to support an occupant's leg when in an extended position.

Abstract: A device for locking a vehicle seat has a pawl which can be pivoted about a first pivot axis and, in a closed position, is in engagement with a positionally fixed fitting and, in an open position, is free from the fitting, wherein the pawl has a first clamping surface, furthermore a locking element for locking the pawl in the closed position, which locking element can be pivoted about a second pivot axis and has a second clamping surface which, in a locking position, bears against the first clamping surface and, in the process, keeps the pawl in the closed position, and, in an unlocking position, is free from the first clamping surface, and an actuating element which interacts with the locking element in order to transfer the locking element into the unlocking position.

Abstract: A rail vehicle and a method for operating the rail vehicle which can be battery-operated contains an intermediate circuit voltage and a battery. The rail vehicle contains a first device for providing an intermediate circuit voltage and a second device for lowering and/or increasing the intermediate circuit voltage between a first and a second voltage level. The second voltage level corresponds to the battery voltage.
