Abstract
Abstract A retaining installation for the passengers of vehicles, especially of motor vehicles, in which the retaining members are substantially not supported at the body of the passengers under any great force during normal driving operation but are supported at the bodies of the passengers at the instant of a collision under still barely tolerable prestress; the retaining members are thereby displaced automatically in the direction toward the passengers upon actuation of brake elements with the build-up of a prestress.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
86 words
A retaining installation for vehicle passengers comprising retaining means for retaining passengers in a vehicle, said retaining means being supported by said passengers with substantially minimal forces during normal operation of said vehicle, brake means for applying braking forces to said vehicle, and control means operatively connected with said brake means for automatically displacing said retaining means toward said passengers such that an increasing prestress is applied to said passengers upon actuation of said brake means until a barely tolerable prestress is obtained on said passengers.
Claim 2
Dependent Claim
86 words
A retaining installation for vehicle passengers comprising retaining means for retaining passengers in a vehicle, said retaining means being supported by said passengers with substantially minimal forces during normal operation of said vehicle, brake means for applying braking forces to said vehicle, and control means operatively connected with said brake means for automatically displacing said retaining means toward said passengers such that an increasing prestress is applied to said passengers upon actuation of said brake means until a barely tolerable prestress is obtained on said passengers.
Claim 3
Dependent Claim
14 words
A retaining installation according to claim 1, wherein said vehicle is a motor vehicle.
Claim 4
Dependent Claim
34 words
A retaining installation according to claim 1, wherein said retaining means include safety belts in which a predetermined substantially constant prestress is applied to at least one belt strap at a predetermined brake force.
Claim 5
Dependent Claim
35 words
A retaining installation according to claim 1, wherein said retaining means include safety belts in which a prestress force correspondingly matched to a respective brake force is applied to at least one belt strap thereof.
Claim 6
Dependent Claim
17 words
A retaining installation according to claim 1, wherein said retaining means are displaced by an auxiliary force.
Claim 7
Dependent Claim
29 words
A retaining installation according to claim 5, wherein said retaining means are hydraulically actuated and adjusting motor means are used which are operatively connected with the said brake means.
Claim 8
Dependent Claim
19 words
A retaining installation according to claim 6, wherein said adjusting motor means are directly connected with said brake means.
Claim 9
Dependent Claim
24 words
A retaining installAtion according to claim 6, wherein said adjusting motor means are connected with said brake means by interposition of pressure converter means.
Claim 10
Dependent Claim
64 words
A retaining installation according to claim 6, wherein said control means includes a spring-loaded piston slidable within a cylinder housing, said piston being connected with one end of a belt of a safety belt system constituting said retaining means, and said cylinder housing being operatively connected with said brake means to displace the piston against the spring force upon actuation of said brake means.
Claim 11
Dependent Claim
30 words
A retaining installation according to claim 5, wherein a servo-system independent of the brake system are included, and adjusting motor means are used which are operatively connected with the servo-system.
Claim 12
Dependent Claim
26 words
A retaining installation according to claim 10, wherein said adjusting motor means are connected with the servo-system by electrically actuated closure means in case of need.
Claim 13
Dependent Claim
20 words
A retaining installation according to claim 1, wherein said retaining means are hydraulically actuated and adjusting motor means are used.
Claim 14
Dependent Claim
46 words
A retaining installation according to claim 12, wherein said adjusting motor means include a belt-force limiting means, said belt-force limiting means limiting the belt force acting on the passenger in case of an accident to a desired value when exceeding a predetermined value during the accident.
Claim 15
Dependent Claim
20 words
A retaining installation according to claim 12, wherein belt-force limiting means are connected in series with said adjusting motor means.
Claim 16
Dependent Claim
25 words
A retaining installation according to claim 14, wherein said belt-force limiting means applies a decreasing belt force with delay upon release of the belt force.
Claim 17
Dependent Claim
25 words
A retaining installation according to claim 15, further including discharge means for discharging a hydraulic actuating medium from the cylinder by way of throttling orifices.
Claim 18
Dependent Claim
34 words
A retaining installation according to claim 16, wherein said retaining means include safety belts in which a predetermined substantially constant prestress is applied to at least one belt strap at a predetermined brake force.
Claim 19
Dependent Claim
35 words
A retaining installation according to claim 16, wherein said retaining means include safety belts in which a prestress force correspondingly matched to a respective brake force is applied to at least one belt strap thereof.
Claim 20
Dependent Claim
64 words
A retaining installation according to claim 1, wherein said control means includes a spring-loaded piston slidable within a cylinder housing, said piston being connected with one end of a belt of a safety belt system constituting said retaining means, and said cylinder housing being operatively connected with said brake means to displace the piston against the spring force upon actuation of said brake means.
