Abstract
Abstract The invention relates to a passive safety belt system for motor vehicles. The belt extends from a point of attachment at the floor of the vehicle via a redirecting fitting attached to the door, to a reel mechanism arranged in the door. In the vicinity of the fitting, a strap is attached to the belt. The outer end of the strap is provided with a block which runs in a track on the upper door window frame. When the door is opened, the block is displaced automatically forward in the track, whereby the strap pulls forward the upper end of the active diagonal portion of the belt, so that it is moved away from the seat.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
152 words
Passive safety belt system for motor vehicles, comprising a belt band, which has an active portion extending diagonally across a vehicle seat from a lower point of attachment at or in the vicinity of the floor of the vehicle via a redirecting fitting which is attached to the rear portion of a window frame of a door adjacent said seat, to a reel mechanism arranged in the door, characterized in that the belt band is joined, in the vicinity of the redirecting fitting, to one end of a strap, the other end of which is provided with a cursor, which is displaceable in a track, which extends along the upper portion of the door window frame, such that, when the opening angle of the door increases, the belt band loads, via the strap, the cursor with a forwardly directed force component, which displaces the cursor towards the front end of the track.
Claim 2
Dependent Claim
