  • Patent number: 7657979
    Abstract: To provide a buckle switch and buckle device wherein a first switch section and a second switch section are unitized to provide improved assembling workability and increased production efficiency. As a tongue plate is inserted to a buckle body to move a slider, a pressing segment 23b of the slider rotates a leaf spring 46 in a direction a and, hence, a depressible portion 44c is depressed to cause a movable member 44 to move in a direction X2. At this time, a stationary contact 71a moves into and is pinched by pinch members 53 of a movable contact 50 disposed on the movable member 44, rendering the switch section SW1 to assume a conductive state. Concurrently, since a magnet M2 is placed in opposition to a magnetic detecting element 61, a second switch section SW2 is switched over. By unitizing the first and second switch sections, assembling workability of a buckle switch 40 to the buckle body can be improved, enabling an increase in production efficiency.

  • Patent number: 7643920
    Abstract: A seat-belt pretensioner arrangement comprises a pretensioner (7) and a control system (3-6) to control the tension applied to a seat-belt by the pretensioner (7). The control system (3-6) controls the pretensioner (7) in response to at least the rate of change of steering angle (??). A first processor (4) provides an output indicating a desired level of force to be applied to the seat-belt determined from the steering angle and the velocity of the vehicle. A second processor (5) provides a corresponding output indicative of a desired force level, determined from the rate of change of steering angle (??) and the velocity of the vehicle (vx). A selector (6) selects the highest of the two force levels, and provides an appropriate signal to the pretensioner (7).

  • Patent number: 7635148
    Abstract: An inflatable air-bag is disclosed which is provided with a controllable vent formed in the fabric of the air-bag. The vent comprises a hole formed in the fabric of the air-bag and a flexible vent tube which extends inwardly of the air-bag from the hole so as to terminate in an open free-end located within the air-bag. The free end of the vent tube is normally tethered within the air-bag so as to maintain the vent in a closed condition but is releasable in response to a signal so as to open the vent. In one arrangement the vent tube is fixed to the inner surface of the air-bag around the hole and is configured so as to have a tapering cross-section which is smaller at the free-end of the tube then at the fixed end of the tube. In another arrangement the vent tube is fixed to the inner surface of the air-bag fabric around the vent hole by stitching which runs around the periphery of the hole and which is located within the vent tube.
