  • Patent number: 4108005
    Abstract: A vehicle deceleration sensing device making it possible to sense whether an occurring collision is powerful or just trivial. The device comprises a first mass body with an actuating member, a second mass body and a blocking member in the form of a cup spring preventing the second mass body from being displaced at an occurring deceleration of the vehicle until the first mass body has been displaced a predetermined distance indicating that the duration and the magnitude of said deceleration are in excess of predetermined values.
    Type: Grant

  • Patent number: 4026189
    Abstract: The invention provides a projectile locking device for a recoilless weapon whereby the projectile is positively locked in a position within the barrel of the weapon so that the projectile cannot be displaced therefrom, for example, in the event that the weapon is dropped accidentally. Previously known devices can cause significant disturbance of the gas flow, causing inbalance of the forwardly and rearwardly directed forces during a firing sequence. The present invention provides a locking device which is of small dimension relative to prior devices so that less disturbance of the gas flow is caused. The invention provides an assembly of a breakable rigid member and a resilient member, one end of which is connected to the projectile and the other end being connected to a holding device in turn connected to the weapon barrel.

  • Patent number: 4015860
    Abstract: There is provided an arrangement for tensioning a strap of a vehicle seat safety harness upon or immediately prior to a collision. The arrangement includes strap tensioning means connected to attachment points of the strap adapted to be actuated by a force generating assembly, which assembly is associated with a sensing device responsive to an impact or an imminent impact on the vehicle for initiating the force. Preferably the strap tensioning means comprises two pistons arranged for mutually opposing movement in a common cylinder, each piston being connected via a line to an attachment point whereby actuation of the means effects simultaneous tensioning at the two points.
