BRIEF SUMMARY
BACKGROUND OF THE INVENTION
For certain vehicle types, such as vehicles where access to a rear seat is through a front door, a conflict develops between the requirement of a correct force geometry for the safety belt in the operating position and the desire for the belt to be completely able to be moved aside to allow access to the rear seat. Previously, attempts were made to solve this problem by anchoring the belt strap in a pivoted arm able to be reset between a forward and a backward folded position. However, certain difficulties have been associated with the resetting of the arm, e.g. when parking on steep inclines. The introduction of a pivoted arm also meant problems of absorbing loads in the pivot axle, as lateral forces are produced during high belt loads.
By means of a device shown in the Swedish Patent Application No. 7709451-4 attempts have been made to solve the earlier problems referred to above. This solution is based on the fact that the lower mounting point on the door side is constructed as an extended bar along which one end of the belt strap is movable. The resetting of the belt strap from the operating position to the moved aside position is done by means of the pull-in force of the reeling device, this force being based on a certain geometry in such a way that the belt strap pull-in force forms a component force striving to move the end of the belt strap along the rod to a moved aside position. However, it has been shown that, after a period of use, this component force will not be sufficient to return the belt strap due to the rod friction, e.g. by dirt accumulation on the rod.
SUMMARY OF THE INVENTION
The purpose of the present invention is to arrive at a device by means of which the problems indicated above are avoided.
This purpose is achieved by means of a device in accordance with the present invention.
In accordance with the invention, there is provided a vehicle comprising, in combination: seat at one side thereof and forming a guide bracket through which the belt strap slides; belt strap for pulling the belt strap through the guide bracket into the reeling device; seat at said one side thereof and forming an elongated bracket extending lengthwise in the travel direction of the vehicle; anchored to the elongated bracket; releasably anchoring a part of the belt strap extending between the lower and upper mountings; and thus limiting wind up of the belt strap on the reel when the belt strap is pulled into the reeling device and located at a spacing from said other end of the belt strap in excess of the spacing between the upper mounting and the elongated bracket; the eye of the belt strap being slidable along the elongated bracket between a first position when the belt strap is anchored to the connecting device; and a second position when the belt strap is released from the connecting device and pulled into the reeling device; the spacing of the first and second positions along the elongated bracket being sufficient to enable the belt strap to be moved aside by sliding the eye along the bracket and thereby facilitate movement of a person into and out from the seat.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be described below, with references made to the appended drawings of which:
FIG. 1 shows a safety belt according to the invention in the operating position,
FIG. 2 shows the safety belt in the moved aside position,
FIG. 3 shows in an enlarged scale part of the safety belt in the operating position as well as in an intermediate position following the disconnection of the safety belt,
FIG. 4 shows a corresponding view of part of the safety belt in the moved aside position, and
FIG. 5 shows in an enlarged scale and from the side part of the safety belt at its upper mounting point.
DETAILED DESCRIPTION OF THE DRAWINGS
A safety belt according to the invention, therefore, is intended for vehicles where access to the rear seat is through the front door openings. FIGS. 1 and 2 show by means of dot and dash lines the interior of such a vehicle while the safety belt
