A vehicle braking arrangement includes a braking plate connected to a vehicle by a link arm. The braking plate is movable from a rest position to a braking position where contact is made with the ground, and includes a sealing rim arranged to at least partially contact the ground such that an at least partly enclosed volume is formed. The vehicle braking arrangement includes an expandable chamber formed between a lower plate, at least one connecting side wall and an upper plate, which chamber is connectable to the volume. Upon activation, the chamber's volume is expanded by movement of the lower plate away from the upper plate. Then the pressure is lowered in the volume which results in that the braking plate is pressed against the ground. In this way, a retaining force is obtained.

Vehicle low pressure brake arrangement

A vehicle braking arrangement includes a braking plate and a link arm arranged to connect the braking plate to a vehicle. The braking plate is movable from a rest position to a braking position where contact is made with the ground. The braking plate is arranged for a first mode of operation, corresponding to the rest position, and a second mode of operation, corresponding to the braking position. In the first mode of operation, the braking plate has a first contact area arranged to face the ground, and in the second mode of operation, the braking plate has a second contact area arranged to face the ground. The second area exceeds the first area.

A vehicle braking arrangement includes a braking plate connected to a vehicle by a link arrangement. The braking plate is movable from a rest position to a braking position where contact is made with the ground, and includes a sealing rim arranged to at least partially contact the ground such that an at least partly enclosed volume is formed. The vehicle braking arrangement includes a low pressure container connected to the volume via a valve assembly. Air pressure in the low pressure container is below the air pressure of ambient air in the rest position of the braking plate. The valve assembly is arranged to be opened when the braking plate is in the braking position such that the pressure is lowered in the volume and the braking plate is pressed against the ground by a conferred pressure difference between air outside the volume and air in the volume.

A safety device for protection of vehicle occupants is described. The safety device exhibits a curtain airbag () located in the area of the roof frame, with an upper edge (), which is rolled up in quiescent state and unrolled in the case of an accident. The curtain airbag can be filled with gas. In order to enable the safety device to be used reversibly, the curtain airbag () is rolled up to roll around its upper edge () when in quiescent state, and the upper edge is held by fixing elements in a manner which the airbag is rotatable.
