Publication number: 20230278524Abstract: The invention relates to a belt retractor surrounding a belt reel which is rotatably mounted in a frame, and comprising a force-limiting device with at least one plastically deformable first torsion rod, wherein the first torsion rod has a first end rotationally fixed to the belt reel and a second end rotationally fixed to a profiled head which can be blocked via a first blocking device in a fixed manner relative to the vehicle. The belt reel, the first torsion rod and the profiled head are arranged coaxially to one another and in series relative to one another.Type: ApplicationFiled: August 30, 2021Publication date: September 7, 2023Inventors: Adrian BUD, Arndt SÖHNCHEN, Lennart PETTERSSON, Ronald JABUSCH, Hans-Jörg LANGHOFF, Antto-Christian GLAESSER, Alexandru CIRSTEA, Elias MATHIASSON, Jens EHLERS, Janne LARSSON, Per AXBLOM

Patent number: 9248803Abstract: A seat belt retractor with a switchable load limiting device for a safety belt of a motor vehicle with a belt shaft and a locking device which upon actuation locks the belt shaft in the belt extraction direction. The load limiting device is located in the force flow between the belt shaft and the locking device between the load limiting levels. A switching device is used for switching the load limiting device. The switching device includes a gas generator for releasing a gas flow into a pressure chamber and an expandable hollow pot which can be driven by the gas flow. The expandable hollow pot is attached to the gas generator in a gas-proof manner and forms the pressure chamber.Type: GrantFiled: November 12, 2011Date of Patent: February 2, 2016Assignee: AUTOLIV DEVELOPMENT ABInventors: Günter Clute, Adrian Bud, Per Axblom, Lena Sandelius

Patent number: 8955784Abstract: A self-locking seat belt retractor has the following components: a locking device (9) which can be actuated in a vehicle-sensitive and/or in a belt webbing-sensitive manner, a belt shaft (1), and a two-stage load limiting device (13) located within the force flow between the locking device (9) and the belt shaft (1). The load limiting device (13) includes a first, high-load limiting element (3) and a second, low-load limiting element (2). The load limitation level can be switched from high to low during load limitation. A third load limiting element (14) parallel to the second load limiting element (2) between the locking device (9) and the belt shaft (1) is formed by at least two structural elements (10, 11, 12, 20a, 20b, 21a-21g, 22a-22g), at least one of which is sheared off during the load limitation.Type: GrantFiled: July 14, 2010Date of Patent: February 17, 2015Assignee: Autoliv Development ABInventor: Per Axblom
