Patent number: 6428039Abstract: A safety arrangement in a motor vehicle comprises a seat to be occupied by a passenger of the vehicle. The seat is supported by a framework (32, 33). The framework is mounted on to a carriage (6) by four deformable members (5) each having sensor means responsive to deformation of the deformable members. The sensor can determine the weight of a person sitting on the seat and also the position of that person within the seat. The sensors are associated with controls adapted to initiate and control the inflation of an air-bag when an accident arises. The inflation characteristic of the air-bag can therefore be adapted to the weight and position of the occupant of the seat.Type: GrantFiled: August 30, 2000Date of Patent: August 6, 2002Assignee: Autoliv Development ABInventor: Anders Pramler

Patent number: 6422592Abstract: A passenger seat air bag module for supporting and deploying an air bag at a location relative to the instrument panel of a vehicle is provided, which includes a housing, an air bag sack, a gas generator for generating gas for inflating the air bag sack, and a cover element for covering a deployment opening through which the air bag sack is moved when it is deployed. To withdraw the cover element, a drive mechanism applies a pulling force to the cover element via a pulling force transmitting element. The drive mechanism includes a drive block having a plurality of paired cylinder bores and associated drive pistons and a push bar driven outwardly by the drive pistons. The outward movement of the push bar effects withdrawal of the cover element from its deployment opening covering position to its withdrawn position by the pulling force transmitting element.Type: GrantFiled: March 2, 2001Date of Patent: July 23, 2002Assignee: Autoliv Development ABInventors: Thomas Reiter, Karl Binknus

Patent number: 6421592Abstract: A safety arrangement in a motor vehicle comprises a safety device (38) adapted to protect an occupant of the vehicle in the case of a roll-over accident, and a roll sensor arrangement to provide a signal (33) to trigger activation of the safety device. A sensor (30) senses an angular parameter such as angular speed about the longitudinal axis of the vehicle, or the actual angle of roll about the longitudinal axis of the vehicle. A further sensor (31) senses a velocity parameter relating to the vehicle speed, such as the total velocity of the vehicle, or the velocity of the vehicle in a predetermined direction. A processor (35) senses an angular speed in excess of a predetermined threshold, which activates a timing mechanism (36) which is associated with a processor (34) which compares angular velocity with a threshold, and provides a triggering signal if the threshold is exceeded. The threshold is a function of vehicle speed.Type: GrantFiled: December 11, 2000Date of Patent: July 16, 2002Assignee: Autoliv Development ABInventors: Jonas Bärgman, Dion Kruse

Patent number: 6416126Abstract: A vehicle seat comprises a squab and a back which is mounted for pivotal movement relative to the squab. The seat incorporates an energy absorbing force limiter adapted to absorb energy as the back of the seat moves rearwardly when subjected to a force from the torso of an occupant of the seat, for example, during a rear impact. The energy absorbing force limiter provides a first resistive force resisting the pivotal movement, and a second resistive force during a second subsequent pivotal movement. The resistive force provided during the first pivotal movement is dependent upon the energy of the rear impact. If the rear impact is low energy rear impact, the resistive force is relatively low whereas if the rear impact is a high-energy rear impact, the resistive force is relative high.Type: GrantFiled: May 23, 2000Date of Patent: July 9, 2002Assignee: Autoliv Development ABInventors: Yngve Håland, Ola Boström

Patent number: 6409217Abstract: A safety-belt arrangement for a motor vehicle has a safety-belt (74) with an end fixing (73) in the form of a plate having an aperture (75). The end fixing may be inserted into a slot (72) formed in a rotatably mounted spool (55). A spring-biased catch (76) is provided which engages the aperture (75) to retain the end fixing in position. When the end fixing is in position a spring catch (70) is released permitting the spool (55) to rotate under the influence of a spring bias. If a severe force is applied to the belt (74), part of the belt is withdrawn from the spool under a force limiting effect. The spool may additionally be associated with a pre-tensioner.Type: GrantFiled: September 27, 2000Date of Patent: June 25, 2002Assignee: Autoliv Development ABInventor: Arnaud Denis

Patent number: 6402239Abstract: A safety device in a motor vehicle comprises a roller retractor (2) mounted at the top of the back (1) of a vehicle seat. The roller retractor (2) has wound on it a sheet-like element or net (3) which is extractable from the roller to engage anchoring means secured in or adjacent the roof of the vehicle. The length of net (3) to be extracted from the roller retractor (2) is different in different positions of the back of the seat. The roller retractor mechanism is associated with a locking mechanism (5) which is actuated in at least one of the alternative positions of the back of the seat to lock the extraction of more than a predetermined length of the sheet-like element from the roller retractor (2). The length is sufficient to enable the sheet to be secured to connecting means provided in the roof of the vehicle.Type: GrantFiled: December 10, 1999Date of Patent: June 11, 2002Assignee: Autoliv Development ABInventor: Lennart Haglund

Patent number: 6367728Abstract: A safety belt winding device is provided having a tensioning mechanism with a cable that can be unwound from a pulley, and also having a force-limiting device for a predetermined belt withdrawal, wherein the connection between the belt winding shaft and the tensioning mechanism is adapted to be eliminated after conclusion of the tensioning movement. A retaining element is disposed on an end of the cable and is releasably fixed in position on the pulley, wherein an ejection arm is mounted on the pulley such that it can be pivoted out radially and that during a tensioning process in a belt winding direction is held in a pivoted-in position by the housing in which the pulley is accommodated. During rotation of the belt winding shaft in the belt withdrawal direction, the ejection arm pivots outwardly and is fixed from further rotation via a configuration of the housing and thereby displaces the retainer element of the cable out of engagement with the housing.Type: GrantFiled: May 11, 2000Date of Patent: April 9, 2002Assignee: Autoliv Development ABInventor: Fredrik Wigström

Patent number: 6354659Abstract: A vehicle seat comprises an inner framework, the inner framework defining a first portion (11, 12, 13, 14) to be received within the squab of the seat and the second portion (15, 16, 17) to be received within the back of the seat. The second portion (15, 16, 17) is mounted on the first portion (11, 12, 13, 14) for rearward pivotal movement about a predetermined pivotal axis (19). Connected between an element (20) which moves in response to movement of the second portion of the framework (15, 16, 17) and the first portion of the framework (11, 12, 13, 14) is an element that provides a mechanical advantage, in the form of a lever arm (27) and a damper in the form of a gas springs (32). The mechanical advantage provided by the lever arm element (27) changes as the second portion of the framework (15, 16, 17) pivots rearwardly about the pivot axis (19). Thus, in a rear impact, an occupant of the seat is given a gradual acceleration.Type: GrantFiled: July 5, 2000Date of Patent: March 12, 2002Assignee: Autoliv Development ABInventors: Tommy Andersson, Timothy Barnett
