Abstract
Abstract A protection system for an occupant seat in a vehicle has a net stored in the headliner above and forward of the front seat. The net is secured at its four corners to cables that are trained along the inside of the vehicle to a pair of pistons in barrels that are located beneath the vehicle. A sensor electrically triggers firing of charges that propel the pistons in the event of a vehicle crash in a wide angle frontal plane. The pistons tension the cables to deploy the net across the front (and sides) of the occupant seat to restrain movement of any occupants in the seat. The cables are latched to maintain the net in its deployed position. A quick release mechanism enables an occupant to release the net after a crash impact or series of crash impacts. Additional protection systems may be provided for additional occupant seats in the vehicle.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
119 words
A protection system for restricting occupant movement with respect to a vehicle subjected to a high impact force from a crash or the like comprising: a net extending across said occupant seat in a stored position out of the normal view of an occupant in said seat; sensing means for sensing a high impact force on said vehicle; means, responsive to operation of said sensing means, for deploying said net against said occupant seat to restrain movement of any occupants seated therein; a plurality of cables connected between said net and said deploying means, said plurality of cables being concealed when said net is in said stored position; and latch means for securing said net in its deployed position.
Claim 2
Dependent Claim
119 words
A protection system for restricting occupant movement with respect to a vehicle subjected to a high impact force from a crash or the like comprising: a net extending across said occupant seat in a stored position out of the normal view of an occupant in said seat; sensing means for sensing a high impact force on said vehicle; means, responsive to operation of said sensing means, for deploying said net against said occupant seat to restrain movement of any occupants seated therein; a plurality of cables connected between said net and said deploying means, said plurality of cables being concealed when said net is in said stored position; and latch means for securing said net in its deployed position.
Claim 3
Dependent Claim
35 words
The system of claim 1 wherein said deploying means includes explosive means mounted to said vehicle, said explosive means including a projectile coupled to said plurality of cables and being activated by said sensing means.
Claim 4
Dependent Claim
20 words
The system of claim 1 wherein said net has a weave sufficiently open to be substantially transparent to an occupant.
Claim 5
Dependent Claim
17 words
The system of claim 1 wherein said net includes reinforced portions for simulating a seat belt restraint.
Claim 6
Dependent Claim
42 words
The system of claim 1 in which said vehicle includes an additional occupant seat located behind said occupant seat and further including another net extending across said additional occupant seat and being deployed responsive to a high impact force on said vehicle.
Claim 7
Dependent Claim
32 words
The system of claim 1, further including means for automatically adjusting said deployed position to accommodate changes in occupant seat location and the number and sizes of occupants in said occupant seat.
Claim 8
Dependent Claim
22 words
The system of claim 1 further including release means, accessible to an occupant restrained by a deployed net, for releasing said net.
Claim 9
Dependent Claim
115 words
A protection system for restricting movement of one or more occupants in an occupant seat of a vehicle that is involved in a crash and subject to one or more impact forces from different directions comprising: sensor means for sensing a high impact force on said vehicle over a frontal angel of about 180 degrees; a net stored out of the normal view of an occupant in said occupant seat; a plurality of cables coupled to said net, said cables being hidden from view when said net is in its stored position; and means for tensioning said cables for deploying and locking said net against said occupant seat responsive to activation of said sensor means.
Claim 10
Dependent Claim
115 words
A protection system for restricting movement of one or more occupants in an occupant seat of a vehicle that is involved in a crash and subject to one or more impact forces from different directions comprising: sensor means for sensing a high impact force on said vehicle over a frontal angel of about 180 degrees; a net stored out of the normal view of an occupant in said occupant seat; a plurality of cables coupled to said net, said cables being hidden from view when said net is in its stored position; and means for tensioning said cables for deploying and locking said net against said occupant seat responsive to activation of said sensor means.
Claim 11
Dependent Claim
21 words
The system of claim 8 wherein said net is stored in the roof of said vehicle, forward of said occupant seat.
Claim 12
Dependent Claim
174 words
A protection system for restricting movement of one or more occupants in an occupant seat of a vehicle that is involved in a crash and subject to one or more impact forces from different directions comprising: sensor means for sensing a high impact force on said vehicle over a frontal angle of about 180 degrees; a net stored out of the normal view of an occupant in said occupant seat; a pair of cables coupled to said net on each side of said occupant seat, all of said cables being hidden from view when said net is in its stored position; means for tensioning said cables for deploying and locking said net against said occupant seat responsive to activation of said sensor means; and each of said pair of cables being connected to a top portion of said net with the bottom one of said pair of cables being releasably secured above said occupant seat and being released upon impact such that said net extends downwardly and rearwardly toward said occupant seat during deployment.
Claim 13
Dependent Claim
174 words
A protection system for restricting movement of one or more occupants in an occupant seat of a vehicle that is involved in a crash and subject to one or more impact forces from different directions comprising: sensor means for sensing a high impact force on said vehicle over a frontal angle of about 180 degrees; a net stored out of the normal view of an occupant in said occupant seat; a pair of cables coupled to said net on each side of said occupant seat, all of said cables being hidden from view when said net is in its stored position; means for tensioning said cables for deploying and locking said net against said occupant seat responsive to activation of said sensor means; and each of said pair of cables being connected to a top portion of said net with the bottom one of said pair of cables being releasably secured above said occupant seat and being released upon impact such that said net extends downwardly and rearwardly toward said occupant seat during deployment.
Claim 14
Dependent Claim
24 words
The system of claim 10 wherein said net has an open weave construction for enabling visibility therethrough and for minimizing air resistance during deployment.
