Abstract
The invention relates to an arrangement and a method for height adjustment of the upper attachment point of a safety belt, arranged in a vehicle with a vehicle seat which is spring-mounted in the vertical direction, where the upper attachment point is arranged displaceably in the vertical direction on the body of the vehicle. Said height adjustment takes place as a function of the springing movement of the vehicle seat, which results in the upper attachment point always remaining correctly positioned in the vertical direction.
Claims11
A height-adjusting arrangement for an upper attachment point of a safety belt wherein the said upper attachment point is affixed to a slide which is displaceably arranged on a guide rail, arranged in a vehicle with a vehicle seat which is spring-mounted so as to move in a generally vertical direction, by means of a mounting arrangement having pairs of intersecting link arms and articulated points of intersection, comprising:
- said upper attachment point being mounted for displacement also in a generally vertical direction in the body of the vehicle adjacent the seat and being connected to said vehicle seat via vertical seat movement transmitting means for causing the spring induced movement of the vehicle seat in said vertical direction to bring about a corresponding vertical displacement of said upper attachment point.
A method for height adjustment of an upper attachment point of a safety belt, located in a vehicle having a spring mounted vehicle seat which displaceable in a generally vertical direction, comprising the steps of:
- locating the upper attachment point for displacement in a generally vertical direction in the vehicle in proximity to the vehicle seat, connecting the vehicle seat to the upper attachment, and displacing the upper attachment point vertically as a function of the vertical spring displacement of the vehicle seat in the form of a mounting arrangement having pairs of intersecting link arms and articulated points of intersection.
