Abstract: The present disclosure relates to a method for controlling a time of activation of a restraint system in a vehicle, the vehicle comprising a seat belt associated to a seat, the restraint system being a reversible restraint system, the method comprising the steps of a) determining a current length (L) of pulled out seat belt, b) detecting a collision or an imminent collision involving the vehicle, c) predicting a time (T0) when the collision is predicted to affect a user of the seat belt, d) activating the reversible restraint system a selectable time period (?1) before the time (T0) when the collision is predicted to affect the user of the seat belt, wherein a length of the selectable time period (?1) is a function of the determined current length (L) of pulled out seat belt. The disclosure further relates to a safety arrangement of a vehicle.

Abstract: An apparatus and method are disclosed for vehicle occupant protection in large animal collisions. Objects forward of the host vehicle are monitored using at least one forward looking remote sensor and object signals output. A velocity of the host vehicle is determined and velocity signals output. The object signals and the velocity signals are processed to determine whether the host vehicle unavoidably will suffer a collision with a large animal while traveling at or above a threshold velocity and a collision signal is output. Operation of a motor operated height adjustment device, an inclination adjustment device and/or a longitudinal position adjustment device of a vehicle seat is triggered to move a seat cushion and a backrest thereof away from a leading edge of a roof of the host vehicle in response to the collision signal.

Abstract: A method is provided for operation of a safety arrangement in a vehicle. The safety arrangement comprises a seat belt, a seat belt retractor and at least one seat position adjustment arrangement for position adjustment of a seat of the vehicle and/or a portion of the seat. The method comprises a refraction of the seat belt by means of the seat belt retractor with a retraction force, and a pre-crash displacement of the seat and/or the portion of the seat resulting in a displacement force acting on the seat belt. The method further comprises adapting the pre-crash displacement and the refraction of the seat belt to each other by ascertaining that a combined seat belt force comprising the refraction force and the displacement force does not exceed a selectable level. The disclosure further relates to a safety arrangement for a vehicle and a vehicle comprising such a safety arrangement.

Abstract: A method and apparatus are disclosed for vehicle occupant protection in unintentional roadway departure by a vehicle having at least one vehicle seat with a seat cushion mounted on a seat frame, the height of which is adjustable through a motor operated height adjustment device. Vehicle travel is monitored using a remote sensor and/or a vehicle dynamics sensor. The remote sensor detects edges of the road. The vehicle dynamics sensor determines vehicle dynamics parameters. Road edge signals and/or vehicle dynamics signals are processed to determine whether the vehicle is about to leave the road. Operation of the height adjustment device to move a seat cushion towards a crash-position is triggered in response to an off-road signal indicating that the vehicle is about to leave the road.

Abstract: A method performed by a retraction control system of a vehicle for controlling refraction of a seat belt of a reversible seat belt refractor arrangement for a vehicle occupant is provided. The control system determines fulfillment of an activation condition based on an initiating input derived from a vehicle situation sensing system, which initiating input indicates that the vehicle, at an initiating time instant, is considered likely to be, or is about to become, involved in a hazardous situation and/or uncomfortable dynamic situation. The control system generates an activation signal utilizable for initiation of retraction of the seat belt. If the control system determines absence of fulfillment of a confirming condition within a predetermined confirming time period, and/or if the control system determines fulfillment of an abort condition within a predetermined abort time period, the control system generates a deactivation signal utilizable for aborting the initiation.

Abstract: A method of activating a passenger safety arrangement of a vehicle, the method including reading in a roll rate of the vehicle and triggering the passenger safety arrangement when, at a first time, at least one roll rate value is present, which exhibits a positive sign and is larger than a roll rate positive threshold value and when, at a second time after the first time, at least one roll rate value is present, which exhibits a negative sign and is smaller than a roll rate negative threshold value.

Abstract: A 4-point occupant restraint belt system for a vehicle seat having a seat bottom and a back rest. A one-piece belt is connected to the vehicle at upper and lower attachment points disposed adjacent a first side of the vehicle seat, and a buckle is disposed adjacent an opposite second side of the vehicle seat. A latch is slidingly mounted on the belt and engagable with the buckle to secure the belt around a seat occupant in a three-point configuration. A lifting arm has a lowered position wherein it is beneath the belt and adjacent the latch when the latch is engaged with the buckle, and the lifting arm is movable to a raised position wherein it raises a portion of the belt to a position adjacent the back rest above the buckle, thereby creating a 4th belt attachment point.
