  • Publication number: 20080054617
    Abstract: The invention relates to a device that after the belt slack present in a belt system has been removed by a tightening system, with the aid of a compressed gas stored in a tank generates a force via a piston/cylinder system in the belt system, which force has the necessary level in the event of an accident to stop the occupant. The impingement of the piston with the compressed gas in the tank can occur through the release of the breechblock piston secured with a blocking pin or also with a projectile destroying a membrane. The compressed gas located in the container can also be brought to the necessary operating pressure by a pyrotechnical propellant charge in the event of a collision, at which pressure a rupture membrane then breaks. The maximum level of the gas pressure can be influenced by a control valve. The reduction of the gas pressure after the end of the collision can be carried out through a throttle opening.

  • Patent number: 6196863
    Abstract: The electrical connection arrangement disclosed in the specification has a housing with two housing parts into which a cable, such a multiconductor flat cable, can be positioned in an at least partially form-fitting manner, and a plurality of insulation piercing contact members which, when moved toward the cable, can displace the insulation of the cable, penetrating into the cable and establishing electrical contact with corresponding cable conductors. In order to provide safe and corrosion-resistant electrical contacts with ring circuits at any location along the ring circuit without cutting the circuit, the ring circuit cable is positioned between the cable piercing contact members and gel is forced from a gel reservoir to which pressure is applied into the openings in the cable insulation to surround the electrical connections with gel.
