Patent number: 10137867Abstract: 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.Type: GrantFiled: April 21, 2015Date of Patent: November 27, 2018Assignee: AUTOLIV DEVELOPMENT ABInventors: Christian Svensson, Dan Bråse, Erik Rydsmo, Jan-Erik Källhammer

Patent number: 10065612Abstract: 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.Type: GrantFiled: March 10, 2015Date of Patent: September 4, 2018Assignee: AUTOLIV DEVELOPMENT ABInventors: Christian Svensson, Dan Bråse, Erik Rydsmo, Jan-Erik Källhammer

Patent number: 9656638Abstract: 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.Type: GrantFiled: April 10, 2013Date of Patent: May 23, 2017Assignee: AUTOLIV DEVELOPMENT ABInventors: Erik Rydsmo, Yngve Håland, Christian Svensson, Dan Bråse

Patent number: 7938439Abstract: A safety device for protection of vehicle occupants is described. The safety device exhibits a curtain airbag (10) located in the area of the roof frame, with an upper edge (10a), 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 (10) is rolled up to roll around its upper edge (10a) when in quiescent state, and the upper edge is held by fixing elements in a manner which the airbag is rotatable.Type: GrantFiled: October 31, 2008Date of Patent: May 10, 2011Assignee: Autoliv Development ABInventors: Erik Hjerpe, Dan Bråse

Publication number: 20100282889Abstract: A pretensioner arrangement for a vehicle safety belt includes a safety belt retractor (12,14) comprising a retractor reel (14) mounted for rotation in a retractor frame (12) and a pretensioner actuator (16) including a first rotary output member (18) connected with the retractor reel by way of a first dutch arrangement, and a second rotary output member (28) connected with the retractor reel by way of a second dutch arrangement, the clutch arrangements being such that the output members (18,28) can apply successive displacements to the retractor reel. The first rotary output member (18) is coupled with a first rotary piston (44) mounted within a working cylinder (42) having a first input (50) for pressurized gas to drive the rotary piston (44) and first output member (18), and the second rotary output member (28) is coupled with a second rotary piston (46) mounted within the same working cylinder (42) which has a second input (51) for gas produced by a pyrotechnic gas generator when the latter is fired.Type: ApplicationFiled: January 16, 2008Publication date: November 11, 2010Inventors: Erik Hjerpe, Dan Bråse
