专利汇可以提供Automatically deployed occupant restraint system专利检索，专利查询，专利分析的服务。并且A restraining system of the passive or nondependent type for passenger vehicles such as cars to protect the occupants of the car against injury or death in the case of sudden deceleration of the vehicle caused by an impact and which comprises a flexible blanket or barrier extending across the seats of the car from side-to-side each of which is automatically extended due to an impact deceleration of the vehicle and is pressed against all occupants of each respective seat with a force extending from approximately the shoulder portion of the human body downwardly over the hip and thigh portion to completely extend over the upper and lower torso of the human body and restrain the torso of the human body from being propelled forwardly or towards the side depending on the direction of impact force on the vehicle. The restraining barrier or blanket for the front seat of the vehicle is normally retained in a folded or stored position conveniently forming a padded portion of the dashboard of the vehicle and thus is normally indiscernable; the restraining barrier or blanket for the passenger or rear compartment of the vehicle is normally stored in the back of the front seat of the passenger vehicle; the sides of the restraining blanket or barrier are provided with reinforcing members which have guide means supported in guides disposed along the inner body panel of the vehicle such as to guide the barrier upon expansion along a prescribed path; the restraining barrier is extended by means of actuators concealed in the vehicle which are connected by tension members to the reinforced sides of the restraining barrier; the actuators are automatically operated by means of an impact sensing device to instantly deploy the restraining barriers out of the stored position within fractions of a second.，下面是Automatically deployed occupant restraint system专利的具体信息内容。

3. In the combination as defined in claim 2, each of said power actuators comprising an expansion chamber and a compression chamber; said longitudinally movable member attached to said pull members being disposed in said expansion chamber; explosive means disposed in said compression chamber and means to automatically ignite said explosive means at the instant of occurrence of said impact conditions to create an expansion force within said compression chamber to cause said high speed longitudinally movable member within said longitudinal expansion chamber to be propelled in a direction rearwardly of said vehicle to thereby deploy said restraint member from its stored position against the bodies of said occupants by means of said pull members.
4. In the combination as defined in claim 3, said means to ignite said explosive member within said compression chamber comprising an electric impact sensor connected to the body of said vehicle; and electrical circuit means including a normally open switch connected between said impact sensor and said explosive means and to a source of electrical current carried by said vehicle so that upon closure of said switch by actuation of said impact sensor said explosive means will be ignited.
5. In the combination as defined in claim 2, said pull members having located at a position corresponding to the door openings, latch side, and automatically engaging hook and eye assembly, that allows normal operation of the doors, but when the tensile member is accelerated, it reliably closes the hook and eye to provide a valid tensile path between the end fittings and actuators.
6. In the combination as defined in claim 2, said pull members having located at a position corresponding to the door openings, hinge side, a spring biased connector between the pull member and the poised end fitting to urge the pull member taught through a bushing in the end fitting, to accommodate normal door swing, said connector providing a shock absorbing function during initial deployment of said restraint member.
7. In the combination as defined in claim 2, said guiding means including: elongated arcuate reinforcements at the upper and lower sides of said restraint member at its opposite ends; each reinforcement including a pair of inturned flanges; a transverse pin interposed between said flanges and extending laterally outward thereof; a manually removable hitch pin extending through said flanges and first pin at one end thereof; elongated guide means on the vehicle structure; the outer end of said pin being guidably nested in said guide means and connected to said pull members.
8. In the combination of claim 7, an enlarged forced distribution plate mounted on each pin interposed between the trim panel and vehicle structure whereby upon receipt of a lateral secondary impact to the vehicle, the respective opposed pairs of force distribution plates are adapted to operatively engage the adjacent trim panel and, thus in turn, uniformly distribute deceleration forces upon the occupant or occupants.
9. In the combination as defined in claim 2, in which said pull members are arranged in cooperating coacting relationship with said guide means to exert a pair of forces on said restraint members outwardly to the sides of said occupants of said seat to pull said occupants rearwardly and downwardly onto said seat.
10. In the combination as defined in claim 1, said restraint member being a net like structure comprised of interwoven high-strength tensile fibers having a horizontal upper and spaced lower high-strength zone connected by an intermediate flexible membrane portion; and lateral sides comprised of high tensile members to proVide a substantially, nonresilient net structure across the midbody portion of said occupants when said restraint member is in deployed position.
11. In the combination as defined in claim 10, said horizontal upper and lower high-strength zones being shaped to curve in transverse cross section away from the bodies of said occupants to thereby provide maximum occupant reaction force distribution across those portions of said bodies of said occupants most able to sustain the relatively high reaction forces against said restraint member.
12. In the combination as defined in claim 11, said horizontal upper high-strength zone comprising a plurality of longitudinal strong inelastic fibers adapted for nonresilient abutment against the upper chest portion of said occupants to pull said occupants backwardly into said seat.
13. In the combination as defined in claim 11, said horizontal lower high-strength zone being comprised of a plurality of strong inelastic fibers adapted when deployed in position for abutment against said lower thigh and pelvic portions of said occupants to move said occupants downwardly onto said seat to thereby counteract effects of rollover and side impact forces.
14. In the combination as defined in claim 10, said high-strength zone being composed of low yield woven fabric, secured to structural end fittings to focus the elemental tensile loads into a hardware path to which the automatic actuator means is releasably secured.
15. In the combination of claim 14, a force distributing padding covering said structural end fittings to minimize the effect of contact of these hardware fittings against parts of the occupant.
16. In the combination as defined in claim 10, in which said membrane portion of said restraining member is provided at one side with an opening for extension of the steering column of said vehicle therethrough when in folded position and for subsequent extension of said restraint member over the steering wheel and the lower arm portions of the driver occupant of said vehicle when said restraint member is deployed, to thereby enable said driver occupant of said vehicle to maintain control of said vehicle.
17. In the combination as defined in claim 1, said seat defining a front seat of said vehicle and said restraint member being normally concealed in folded condition along the dashboard of said vehicle.
18. In the combination as defined in claim 1, said seat defining a rear compartment seat of said vehicle and said restraint member being normally concealed in the back structure of the front seat of said vehicle.
