Publication number: 20240025371Abstract: A pedestrian protection device for a motor vehicle having a windscreen and an A-pillar extending adjacent a side edge of the windscreen. The protection device comprises a base member securable to the A-pillar of the motor vehicle, and a trim member moveable relative to the base member. A deployment mechanism is operable upon actuation of the device to drive the trim member away from the base member from an initial position in which the trim member is proximal to the base member, to a deployed position in which the trim member is spaced from the base member. The deployment mechanism comprises a plastically deformable member interconnecting the base member and the trim member and which is arranged, in said deployed position of the trim member, to absorb impact energy arising from impact between a pedestrian and the trim member in compression.Type: ApplicationFiled: September 6, 2021Publication date: January 25, 2024Inventors: Erik RYDSMO, Mikael ANDERSSON

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: 9527476Abstract: A vehicle seat belt retractor with a belt shaft (10) and a coupled profile head lockable to a housing. A force-limiting device has at least two elements (11, 12) between profile head and belt shaft (10). Free ends (15, 16) of the force-limiting elements (11, 12) are coupled to each other by a connecting tube (13) via a coupling element (18). The coupling element (18) has a hook-shaped spring element with a locking hook (19) which slides over the connecting tube (13) when the belt shaft (10) rotates and engages in a locking groove (20) to couple the connecting tube (13) to the belt shaft (10). At a preset angle of rotation of the belt shaft (10) is reached, the bridging device releases the coupling element (18) for the locking hook (19) to latch into the connecting tube locking groove (20).Type: GrantFiled: August 12, 2013Date of Patent: December 27, 2016Assignee: AUTOLIV DEVELOPMENT ABInventors: Fredrik Wigström, Elias Mathiasson, Erik Rydsmo
