  • Patent number: 6183004
    Abstract: A gas bag covering arrangement comprises a gas bag covering for covering an unfolding opening in a vehicle and a device for detachably fastening at least one part of the gas bag covering to the vehicle. The device has at least one holding section and the gas bag covering has a portion which covers the gas bag unfolding opening and which has an edge on which the holding section engages. The device is so flexible that the gas bag covering can move out from its mounting formed by the holding section when the gas bag unfolding opening is exposed. The device further comprises a tear-open section and a mounting section, the tear-open section being destroyed on exposure of the gas bag unfolding opening and on displacement of the holding section such that the flexibility of the device being increased. The holding section remains secured to the device by the mounting section after destruction of the tear-open section.

  • Patent number: 6170860
    Abstract: A gas bag for a vehicular occupant restraint system comprises two plies of fabric partially interwoven along their outer edges. To offer protection over a lengthy period in time amounting to several seconds but nevertheless dissipate the energy of impact to the required degree on impact and cushioning of the occupant, the plies of fabric are substantially air-tight, and the volume of the gas bag is divided by partial interweaving of the plies of fabric within the outer edges into several chambers. Further, the chambers are interconnected by at least one choked port remaining between the portions of the interwoven plies of fabric. Only part of the chambers is directly inflated by an inflator, the remaining part of the chambers being indirectly inflated via the choked port.

  • Patent number: 6164699
    Abstract: A unit comprising a deflection fitting and an automatic adjusting device for safety belt systems in vehicles having at least one seat adjustable in longitudinal direction of the vehicle. The adjusting device has a traction transfer device with two ends, the first end of which being arrested on the seat and the second end of which being coupled with the deflection fitting, a locking device which is intended to prevent a displacement of the deflection fitting in the case of restraint, and a spring element on which the second end of the traction transfer means is arrested. The spring element is in turn fastened to one of the deflection fitting and a sliding carriage to which the deflection fitting is affixed. The spring element yields elastically in order to permit a relative movement of the traction cable and the deflection fitting upon an abrupt introduction of force into one of the deflection fitting and the traction cable.

  • Patent number: 6164696
    Abstract: A gas bag restraint system for vehicle occupants has a multi-stage gas generator and a gas bag which includes an outer wall having wall portions and having at least one fold which is formed by a first holding element. The gas bag is able to gradually take up various discrete inflation volumes in accordance with activated stages of the gas generator and dependent on an internal pressure of the gas bag. The outer wall has the at least one fold in a first, partially inflated state of the gas bag, after ignition of a first stage of the gas generator. In the first state, the outer wall has a portion defining an inflated region of the gas bag and a portion defined by the at least one fold. The fold in the first state is turned over toward the inflated region of the gas bag and is secured by the first holding element to the portion of the outer wall defining the inflated region for forming an inwardly extending pocket.

  • Patent number: 6161864
    Abstract: A gas bag module of a vehicle occupant restraint system comprises a housing, a gas bag arranged therein, a gas generator for filling the gas bag with compressed gas, and a cover which in a closed position closes the housing and can be brought into an opened position after activation of the gas generator so that the gas bag can emerge from the housing. The cover is coupled to a support element which is spatially separate from the cover. The support element, after activation of the gas generator, is exposed to a force resulting from the compressed gas produced by the gas generator and biases the cover into the opened position.

  • Patent number: 6158685
    Abstract: A blocking mechanism for a seat belt retractor has a belt reel (10) rotatably mounted in a frame (12), a ratchet toothing (16) arranged on the frame, a ratchet pawl (24) arranged on the belt reel (10) for cooperation with the ratchet toothing (16) and an inertial disc (20) used as a belt webbing-sensitive sensor element. The inertial disc (20) is rotatable relative to the belt reel (10). The ratchet pawl (24) is pivotally mounted on the inertial disc (20). The belt reel (10) has an actuating element (26a) engaging the ratchet pawl (24). In operation, the actuating element (26a) causes the ratchet pawl (24) to engage with the ratchet toothing (16) when the belt reel (10) is rotated relative to the inertial disc (20).

  • Patent number: 6155595
    Abstract: A knee protection device for vehicle occupants comprises a gas bag having a gas bag wall with opposing sections. The gas bag, in its installed and inflated state, extends in front of the knees of the occupant of the vehicle, lies against the knees in the case of restraint and is intended to largely prevent the knees from moving forward. The device further comprises means in the gas bag which connect the opposing sections of the gas bag wall. The means are fixed to the sections of the gas bag wall and are arranged in such a way that they counteract a change of shape of the gas bag on plunging in by the knees.
