Abstract:
The present invention relates to a pre-tensioner arrangement (1) for use in a motor vehicle safety device, comprising a piston member (3) dispiaceable in a chamber (2) upon a gas pressure applied to said chamber (2) through an inlet (9) and connectabie to a part of a motor vehicle safety device. The pre-tensioner arrangement (1) has a first mode of operation and a second mode of operation. The present invention aims at providing an improved pre-tensioner arrangement.
Abstract:
The present invention relates to a heat exchanger arrangement (4) arranged to be mounted to a vehicle (1). The heat exchanger arrangement (4) is arranged to conduct heat from at least one component (2, 3) in the vehicle (1) to ambient air. The heat exchanger arrangement (4) is arranged to be expandable from a first state (S1) to a second state (S2). Furthermore, the heat exchanger arrangements volume and heat conductivity is increased when the heat exchanger arrangement (4) is expended from the first state (S1) to the second state (S2).The present invention also relates to a corresponding method.
Abstract:
A safety arrangement is provided in a motor vehicle. The motor vehicle has a floor pan (1 ) terminating at its forward end with an inclined splash-wall (3, 4, 5). There is a moveable floor element (10) which has regions (12, 13, 14) which initially conform to and lie adjacent the splash-wall. There is a drive arrangement (15) associated with an accident sensor (16) to drive the moveable floor element rearwardly to a predetermined position. There is a fixed platform (17) located above a horizontal part of the floor pan to be located beneath the foot of a vehicle occupant and to provide a secure point for operation of a pedal. The movement of the moveable floor element (10) is restricted so that no part of the movable floor element impedes movement of a foot pedal (6) to the fully depressed condition.
Abstract:
An air-bag (10) is provided for protecting an occupant of a seat of a motor vehicle. The air-bag is to be mounted to the vehicle by mountings (11). When inflated the air-bag extends downwardly from the roof of the vehicle to occupy a position in front of an occupant of the seat of a vehicle. Each mounting (11) is adapted to release the inflatable element (10) in response to a force having a substantial forward component applied to the air-bag, or in a response to an accident situation when a seat of the vehicle is occupied by an un-belted seat occupant. If there is an un-belted occupant, the air-bag in front of the occupant will be disconnected from the roof, preventing undesirable neck injuries occurring. If the seat occupant is belted, then the air-bag will remain in position in front of the occupant.
Abstract:
A seat-belt pre-tensioner for a motor vehicle, comprises a piston member 28, 102 displaceable in a chamber 38, 40, 104 under gas pressure from a source of compressed gas or a source of gas generated by a pyrotechnic device applied to said chamber. The piston member is coupled to a seat belt tensioning element. In one arrangement, the piston is a rotary piston in the form of a vane 28 secured to a shaft 30 carrying a crank 50 having at its end a member 54 retaining a loop at one end of a seat belt tensioning cable 56. In another arrangement the piston 102 is movable axially in a cylinder 104 and acts on an eccentrically mounted drum 112 around which a seat belt tensioning cable 130 extends.
Abstract:
A height-adjustment mechanism for adjusting the height of a safety belt loop (6) on a pillar (4) or other structure in a motor vehicle includes a moveable member (12, 12a) carrying the loop, the member (12,12a) being guided for vertical movement on the pillar (4) by pneumatic means for height adjustment. The mechanism includes means (15,26,47,49) for resisting or preventing alteration of the height of the pillar loop (6) on the pillar (4) in response to forces applied by the safety belt (8) in an accident situation. The pneumatic means may comprise a pneumatic piston and cylinder unit (18) or may comprise a rotary pneumatic motor (41 ) driving a screw (35) directly or via gearing.
Abstract:
A safety system is disclosed for use in a motor vehicle which comprises a source of compressed gas (19) and at least one safety device (9, 10, 11 ). A sensor arrangement (4,5) is provided, together with a control unit (7). The or at least one safety device (9,10,11) is operatively connected to the source of compressed gas (19) so as to be pneumatically operable. The system is characterised in that it comprises a pyrotechnic charge (21) and the or at least one safety device (9,10,11) is operatively connected to the pyrotechnic charge (21) so as to be pyrotechnically operable. The control unit (7) is configured to actuate the or each pneumatically-operable device upon receipt of a first signal from the sensor arrangement (4,5), and to actuate the or each pyrotechnically- operable device upon receipt of a second signal from the sensor arrangement (4,5).

The present invention also relates to a corresponding method.
Abstract:
There is disclosed a dummy test vehicle (10) having running gear (26, 27) configured to permit the vehicle to run along the ground (17). The running gear comprises a guide arrangement (27) configured for connection to and movement along a track (18) secured to the ground (17). The guide arrangement (27) comprises a carriage (25) which is configured for connection to the track (18) in a manner effective to vertically secure it to the track (18) for movement along the track, and a support (36) associated with the structure (14) of the vehicle, wherein the carriage (35) and the support (26) are releasably connectable to one another. In a preferred arrangement, the carriage (35) and the support (26) are magnetically connectable.
