Abstract

Abstract The device comprises an angle lever having two arms pivotally supported in a door of a vehicle. One of the arms is connected to the vehicle body via force transfer means, which causes the lever to pivot when the door is opened, moving a tension line between the other arm thereby allowing a spring loaded connecting link to remove or apply the belt.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 212 words
A passive actuating device for a safety belt associated with a vehicle passenger comprising, in combination: a. an angle lever having a first arm and a second arm, the angle lever being pivotally mounted in a door of a vehicle; b. force transfer means coupling the first arm to the body of the vehicle for pivoting the angle lever as the door is opened and closed; c. a tension line arranged in the door and coupling the second arm to the safety belt; d. roller means arranged in the door for changing the direction of the tension line; e. spring means being in connection with the end of the tension line which is coupled to the safety belt for biasing the safety belt away from a passenger holding position so that the safety belt will be in a passenger holding position when the door is closed and will rise upward to a free position when the door is opened, the angle lever being oriented with respect to the roller means such that the angle between the second arm and the portion of the tension line extending between the second arm and the roller means is at a minimum when the door is closed and increases to a maximum as the door opens.
Claim 2
Dependent Claim 212 words
A passive actuating device for a safety belt associated with a vehicle passenger comprising, in combination: a. an angle lever having a first arm and a second arm, the angle lever being pivotally mounted in a door of a vehicle; b. force transfer means coupling the first arm to the body of the vehicle for pivoting the angle lever as the door is opened and closed; c. a tension line arranged in the door and coupling the second arm to the safety belt; d. roller means arranged in the door for changing the direction of the tension line; e. spring means being in connection with the end of the tension line which is coupled to the safety belt for biasing the safety belt away from a passenger holding position so that the safety belt will be in a passenger holding position when the door is closed and will rise upward to a free position when the door is opened, the angle lever being oriented with respect to the roller means such that the angle between the second arm and the portion of the tension line extending between the second arm and the roller means is at a minimum when the door is closed and increases to a maximum as the door opens.
Claim 3
Dependent Claim 20 words
The passive actuating device defined in claim 1, wherein said minimum value of said angle is at least approximately 90*.
Claim 4
Dependent Claim 20 words
The passive actuating device defined in claim 1, wherein said maximum value of said angle is at least approximately 180*.
Claim 5
Dependent Claim 47 words
The passive actuating device defined in claim 1, wherein said angle lever is mounted at a region of the door on the hinge side thereof, and wherein said door includes a guide for the safety belt at a region thereof which is opposite to said hinge side.
Claim 6
Dependent Claim 16 words
The passive actuating device defined in claim 1, wherein said guide extends at least approximately vertically.
Claim 7
Dependent Claim 35 words
The passive actuating device defined in claim 1, wherein said roller means is arranged in the door at least approximately below the point at which the safety belt is attached when in the passenger-holding position.
Claim 8
Dependent Claim 73 words
The passive actuating device defined in claim 1, wherein the roller means comprises a pair of concentric rollers which are coupled for rotation, one with the other, and one of which has a smaller diameter than the other; and wherein said tension line comprises a first portion extending between the second arm of the angle lever and the smaller roller, and a second portion extending between the larger roller and the safety belt.
Claim 9
Dependent Claim 57 words
The passive actuating device defined in claim 1, wherein said spring means comprises a tension spring; and wherein said device further comprises: a second tension line arranged in the door and coupling said tension spring to the safety belt; and a second roller means arranged in the door for changing the direction of the second tension line.
Claim 10
Dependent Claim 35 words
The passive actuating device defined in claim 8, wherein said second roller means is mounted in such a way that the path of motion of the connecting point of the safety belt is tangent thereto.
Claim 11
Dependent Claim 71 words
The passive actuating device defined in claim 8, wherein sAid second roller means comprises a pair of concentric rollers which are coupled for rotation, one with the other, and one of which has a smaller diameter than the other; and wherein said second tension line comprises a first portion extending between said tension spring and the smaller roller, and a second portion extending between the larger roller and the safety belt.
Claim 12
Dependent Claim 17 words
The passive actuating device defined in claim 1, wherein said force transfer means is a door stop.
