A seat-mounted airbag assembly (1000) is provided. The assembly comprises a first lateral airbag (101A) configured to deploy adjacent to a first side of a vehicle seat (1) and a first wrap-around belt (201A) extending from an upper portion of a seat back (3) to a tensioning device (300) arranged at least partly underneath a seat pan (5). The first wrap-around belt (201A) is configured to be tensioned and form a reaction surface to the first airbag (100A). A lower end of the first wrap-around belt (201A) extends along a surface of the seat pan (5) towards a lower side of the seat pan (5) where it connects to the tensioning device (300). A portion of the lower end of the first wrap-around belt (201A) is received in a first tube (10A).

A seat-mounted airbag assembly (1000A; 1000B) is provided. A seat-mounted airbag assembly comprises a lateral airbag (101A; 101B) supported by a lateral side of a vehicle seat (1); a tensioning device (300); and a wrap-around restricting member (200A; 200B). The restricting member extends across the lateral airbag. The wrap-around restricting member is configured to be tensioned by the tensioning device (300) to thereby form a reaction surface to the lateral airbag upon inflation and deployment of the lateral airbag. The wrap-around restricting member (200A; 200B) has a longitudinal extension where the member along a first longitudinal portion (P1) is formed by a belt (204) and along a second portion (P2) is formed as a cord (205).

A seat-mounted airbag assembly (1000A; 1000B) is provided. The assembly comprises a lateral airbag (101A; 101B) supported by a lateral side of a vehicle seat (1) and a tensioning device (300) arranged at a seat pan (5) of the vehicle seat (1). The assembly also comprises a wrap-around restricting member (200A; 200B) that extends across the lateral airbag from an upper portion of a seat back (3) of the vehicle seat to the tensioning device. The wrap-around restricting member is configured to be tensioned by the tensioning device to thereby form a reaction surface to the lateral airbag upon inflation and deployment of the lateral airbag. The assembly further comprises a spring biased pre-tensioning bracket (400A; 400B) that is arranged to engage and maintain the wrap-around restricting member in a pretensioned condition during normal operation of the vehicle seat. The pre-tensioning bracket is configured to release its engagement with the wrap-around restricting member upon actuation of the tensioning device.

The present disclosure relates to a computer-implemented method for training of a machine-learning model in vehicle safety action assessment for a vehicle (1) adapted to travel in a forward movement direction (D). The method comprises preparing (S100) training data, which in turn comprises obtaining (S110) sets of sensor data used for determining movement data (120, 122, 130) for a vehicle driver (8) and optionally also for the vehicle (1). The method further comprises training (S200) the machine-learning model using the prepared training data by associating (S210) each set of sensor data with a safety action among a plurality of safety actions. The associating (S210) comprises setting (S211) a threshold level (T1, T2, T3) for each determined movement data (120, 122, 130), where each threshold level (T1, T2, T3) corresponds to a certain safety action.

The present disclosure relates to a computer-implemented method for training of a machine-learning model in vehicle accident warning level assessment for a two-wheeled or a three-wheeled vehicle (1) that is adapted to travel in a forward movement direction (D). The method comprises preparing (S100) training data, where preparing (S100) training data comprises obtaining and automatically acquiring (S110) a plurality of sets of sensor data (100), each set of sensor data (100) being collected during a corresponding time period. The method further comprises training (S200) the machine-learning model using the prepared training data, where training (S200) the machine-learning model comprises associating (S210) each set of sensor data (100) with a certain warning level (170), among a plurality of warning levels.

An inflatable airbag (1; 1'; 1") forming part of a vehicle safety system or a wearable is provided. The airbag comprising a first wall (10) and a second wall (20) that are mutually joined along an outer perimeter (11, 21) to form a closed airbag. The first wall comprises a first wall portion (12) and a second wall portion (13), where a first edge portion (14) of the first wall portion (12) is joined to a first edge portion (15) of the second wall portion (13). The second wall (20) comprises a first wall portion (22) and a second wall portion (23), where a first edge portion (24) of the first wall portion (22) is joined to a first edge portion (25) of the second wall portion (23). The first edge portions of the first and second wall portions of the first wall each have a sub-portion (14a, 15a) having a convex extension. The first edge portions of the first and second wall portions of the second wall each have a sub-portion (24a, 25a) having a concave extension. Also, a method of providing such airbag is disclosed. The invention also refers to the use of such airbag.

Load absorption device (100) to be used with a vehicle seat (200) is provided. The device comprises a rail arrangement comprising an upper rail (1) configured to be connected to a lower side of the vehicle seat (200), and a lower rail (2) configured to be fixedly connected to a top surface of a vehicle floor. The upper and the lower rails are slidingly connected to each other to allow a longitudinal mutual displacement between the upper rail and the lower rail. The device further comprises a bracket (4) fixedly connected to the lower rail or configured to be fixedly connected to a floor of the vehicle, a strip (3) having first leg (15A) having a first end (16A), a second leg (15B) having a second end (16B), and a curved portion (15C) intermediate the first and second legs, and a locking arrangement having a first sub-arrangement (5) being fixedly connected to the bracket, and a second sub-arrangement (6) being releasably connected to the first sub-arrangement. The first leg is slidably arranged in the bracket, and the second leg is fixedly connected, directly or indirectly, to the upper rail and to the second sub-arrangement. Upon an actuation of the locking arrangement, the connection between the first and the second sub-arrangements is released, whereby the second sub-arrangement, the second end of the strip and the upper rail are allowed to displace in a first direction away from the bracket while the first end of the strip is allowed to translate in a second direction. Further a vehicle occupant protection system and a method of operating such system is provided.

Die Erfindung betrifft einen Sitz (200), ausgebildet als ein Fahrzeugsitz (100), wobei der Sitz (200) mindestens:- ein Sitzteil (102),- eine mit dem Sitzteil (102) verbundene Rückenlehne (104) und- einen Sicherheitsgurt (204) aufweist, welcher ein Gurtband (206) zum Rückhalten eines auf dem Sitz (200) sitzenden Insassen oder einer auf dem Sitz (200) angeordneten Attrappe umfasst,wobei das Gurtband (206) sich zwischen zwei unteren Gurtverankerungspunkten (208) und einem oberen Gurtverankerungspunkt (210) erstreckt,wobei während einer erhöhten Krafteinwirkung, insbesondere einer prüfbedingten Krafteinwirkung, auf den Sitz (200) die beiden unteren Gurtverankerungspunkte (208) vorverlagerbar ausgebildet sind.
