  • Patent number: 4275901
    Abstract: An inflatable safety bag system for vehicles which comprises an electrical actuator device for detecting a vehicle collision, a mechanical actuator device for detecting a vehicle collision, and a valve opening device for a high-pressure gas container for supplying high-pressure gas to a safety bag at the time of a vehicle collision. The electrical and mechanical actuator devices are operatively connected to the valve opening device, and are actuatable independently of each other. The valve opening operation of the high-pressure gas container is effected in response to actuation of at least one of the electrical and mechanical actuator devices. When the electrical actuator device fails to operate, the mechanical actuator device enables the safety bag to be inflated, thereby ensuring positive and reliable operation of the safety bag system.

  • Patent number: 4270764
    Abstract: A noise-making device which is particularly adapted to be utilized in conjunction with a skateboard or similar wheeled vehicle. The device comprises a ring-shaped component having one or two cylindrical projections extending from the outer peripheral edge thereof in a direction parallel to the axis of the ring. The other side of the ring is fastened to the end wall of a rotatable wheel, such as a skateboard wheel. The other component of the device comprises a somewhat rectangular, flat piece of metal having a pair of rounded edges and a hole in the center. This component is fastened to the wheel support device so that an edge of the metal piece is adjacent the end surface of the wheel. As the wheel rotates, the projections from the rotating component intercept the stationary plate to flex same, thereby creating sound.

  • Patent number: 4266803
    Abstract: A ski brake arrangement having a U-shaped spring wire member pivotally secured to the upper surface of a ski about an axis which extends substantially perpendicularly with respect to the longitudinal axis of the ski. Each leg of the U-shaped spring wire has a braking blade thereon. The pivotal support for the U-shaped spring wire is composed of a block having a shaft member thereon, which shaft extends parallel to the aforementioned axis and is received in an opening of a two-arm toggle lever pivotally secured to the ski about a further axis which extends parallel to the longitudinal axis of the ski. The innermost arm of the toggle lever is operatively engaged with a pedal pivotally secured to the ski so that during a downward movement of the pedal, the toggle lever will be pivoted about its pivotal support to cause an upward and inward movement of the block member.

  • Patent number: 4266630
    Abstract: In a forward engine compartment of a vehicle a power unit is suspended so as to have a controlled rearward movement in the engine compartment when exposed to excessive forces in the lengthwise direction of the vehicle during a collision. There is at least one rear mounting having a resilient body separating two members secured to the power unit and to structural portions of the vehicle body, respectively. Said rear mounting allows one of the members a limited movement relative to the other while absorbing deformation work. As the power unit travels further back the attachment of the rear mounting is gradually destroyed, but it holds long enough to allow the power unit to hit a cowl panel at the rear of the engine compartment, thus controlling the travel of the power unit.

  • Patent number: 4262557
    Abstract: Since the maximum jolt amplitude during gear shifts in an automatic transmission occurs when a frictional clutch band is first holding fully and since a mathematical relationship can be established between this maximum amplitude and the amplitude of the jolt while the band is slipping, the maximum permissible jolt amplitude during slippage (R.sub.O) is calculated as a function of the input and output speed of the transmission at the start of the gear shift and the predetermined maximum permissible over-all jolt amplitude (R.sub.max). The actual jolt amplitude is determined continuously, compared to R.sub.O, and the friction band is activated to maintain the actual jolt equal to R.sub.O, while the band is slipping.
