Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
67 words
Safety belts for vehicles comprising a vehicle, a safety belt being connected to anchoring points on vehicle and having belt portions of a hose like configuration capable of being expanded by a pressure medium, valved means capable of supplying a pressure medium to said belt portions, means for the directional guiding of said belt portions, and clamping means capable of squeezing said belt portions at given points.
Claim 2
Dependent Claim
67 words
Safety belts for vehicles comprising a vehicle, a safety belt being connected to anchoring points on vehicle and having belt portions of a hose like configuration capable of being expanded by a pressure medium, valved means capable of supplying a pressure medium to said belt portions, means for the directional guiding of said belt portions, and clamping means capable of squeezing said belt portions at given points.
Claim 3
Dependent Claim
38 words
Safety belt as claim in claim 1 wherein each hose-like belt portion has at least one flexible pressure medium channel extending longitudinally of said belt portions which channels tend to resist deformation with respect to their crosssectional configuration.
Claim 4
Dependent Claim
22 words
Safety belt as claimed in claim 1 wherein at least one of said anchoring points in on a door of said vehicle.
Claim 5
Dependent Claim
35 words
Safety belt as claimed in claim 3 wherein said clamping means is capable of guiding at least one of said belt portions, towards said door upon the opening of said door relative to said vehicle.
Claim 6
Dependent Claim
30 words
Safety belt as claimed in claim 1 wherein said clamping means are arranged at least on one of said anchoring points and capable of pivoting around a substantially vertical shaft.
Claim 7
Dependent Claim
37 words
Safety belt as claimed in claim 1 wherein said directional guiding means comprising at least two horizontal shafts connected to said vehicle anchoring points and means connected to said belt portions and pivotally mounted on said shaft.
Claim 8
Dependent Claim
33 words
Safety belt as claimed in claim 1 wherein said valved means includes a regulation valve arranged to create a difference in pressure on said belt portions on two sides of said clamping device.
Claim 9
Dependent Claim
45 words
Safety belt as claimed in claim 7 wherein said valve is capable of connecting one of said belt portions on one side of said clamping means with said pressure medium and the belt portion on the other side of said clamping means with the atmosphere.
Claim 10
Dependent Claim
37 words
Safety belt as claimed in claim 7 wherein said valve is capable of bringing the belt portions on opposite sides of said clamping device, into communication with each other and discontinueing their communication with said pressure medium.
Claim 11
Dependent Claim
51 words
Safety belt as claimed in claim 7 wherein said regulation valve comprises a valve housing having a circular cross-section with a plurality of peripherically located connection openings and a valve member located in said valve housing which valve member is capable of selectively maintaining and interrupting communication between said connection openings.
Claim 12
Dependent Claim
16 words
Safety belt as claimed in claim 10 wherein said valve member has a substantially H-shape configuration.
Claim 13
Dependent Claim
43 words
Safety belt as claimed in claim 7 including means capable of feeling abnormal changes in the motion of said vehicle and increasing the pressure of said pressure medium to counteract the pulling force on the safety belt due to such change of motion.
Claim 14
Dependent Claim
35 words
Safety belt as claimed in claim 12 including a G-sensitive switch and a pyrotechnic pressure generating means in communication with a belt portion on one side of said clamping device and igniteable by said switch.
