Abstract

Description

Holding devices for stored heads - seat belts in vehicles Nowadays, every driver or occupant is used to putting on a seat belt for his / her body before starting a journey. The seat belt for the head is still not common today, but is necessary because the previous solutions with the help of the air bags are unsatisfactory, especially because the vehicles are getting faster and faster and air bags are only used up to an impact speed of 50 km / h successfully help. Problem with the head - seat belts in addition to the body belt must be designed in such a way that they are easy to use for the person using them in order to achieve a high level of acceptance. This also means that the head seat belt can be easily removed after use. When not in use, the head seat belt must also be fastened in such a way that there is no potential for injury to the occupants during braking maneuvers or the like. PRIOR ART The patent FR 2 721 880 A1 (2) from 07/01/1994 by Brossard shows a depression in the upper area of ​​the backrest of a vehicle seat with a latching mechanism for a fastening element (protective helmet) for a head safety belt to be put down. Invention The present innovations are based on the assumption that the approx. 2 cm wide head safety belt in its front half of the forehead consists of a fixed splint with padding towards the forehead skin. The forehead half of the head safety belt is, so to speak, a padded bracket. As a solution, the following three holding devices for locking unused, stored head - seat belts while driving in a vehicle are proposed: 1. Solution: In vehicles with a large distance between the driver's head and the vehicle roof, a holding frame is built on the upper end of the backrest. This frame has a hook-shaped holder on which the fixed forehead strap bracket can be hung after use. A slight retraction force of the head seat belt through the belt retractor keeps the removed head belt in a taut position on this hook and thus does not fall down when the vehicle is jolted or when the vehicle is braking, because the end of the hook is bent upwards and slightly inwards. 2. Solution: In vehicles with only a small distance between the head of the occupant or the head end of the backrest / headrest and the vehicle roof, a storage recess is provided in the shape of a curve in the head part of the backrest. The arch has the radius of the front, fixed half of the head seat belt. At the highest point of this arched recess in the backrest there is a catch with a retaining slot and a spring-loaded counter-pressure lever. This resilient counter-pressure lever ensures that the fixed part of the head safety belt is firmly locked in the opposite gap. The counter-pressure lever can exert its pressure in the direction of the holding slot by means of an elastic spring (as shown in FIG. 3) or also an elastic plastic bracket (not shown). 3rd solution: Under the vehicle conditions as in solution 2, a step is provided for locking into the arched recess of the backrest. In this solution, however, the resilient holding mechanism is attached to the front part of the fixed head seat belt: An upper and a lower clamping spring ensure locking in the intended holding slot, which is attached laterally, i.e. outside the center, on both sides to match the points of the Clamp springs. To remove the head seat belt from this locking mechanism, the driver must use one hand to squeeze a pair of clamps on one side between thumb and finger (s). The head seat belt can then be removed upwards. The above-mentioned three embodiments of the subject matter of the invention are explained in the following description with reference to the embodiments shown in simplified form in the accompanying drawings. They show: Fig. 1: 1. Solution in side view of a shelf - holding device with mounting frame on top of the head end of a backrest; Dashed illustration: in function on the driver's head, solid lines: storage position in the holding device. Fig. 2: 2nd solution: Holding device integrated in the head end of a backrest with a resilient counter-pressure lever in the storage recess for the purpose of locking: a) head seat belt in use by an occupant while driving, b) head seat belt in unused storage position in the holding device. 3: Cross-section in the middle of the holding device from FIG. 2 at the highest point of the arched storage trough: A counter-pressure lever with elastic suspension pushes the fixed front part of the head seat belt to be inserted into the holding slot. Fig. 4: 3rd solution: Holding device integrated in the head end of a backrest: The resilient holding mechanism is built into the fixed front part of the head seat belt: a) View of the head seat belt from the front with a translucent, dashed suspension mechanism as well as a continuously drawn, externally visible Pairs of clamps, b) cross section of the locked, stored head seat belt at the level of the sectional plane indicated in Fig. 4 a). In Figure 1, the 1st solution of a holding device for a stored head seat belt (1) is shown: A mounting frame (3) is built on the head end of the backrest (16) of a (car) driver's seat. At the upper end of this mounting frame (3) a storage trough (8) with a hook-shaped cross-section for hanging up the head safety belt is attached in the direction of travel. This storage trough (8) at a suitable distance allows the seat belt (7) to rest firmly and safely due to the retraction force of the belt retractor. To remove the head seat belt, the driver or occupant pulls the head seat belt up slightly against the retraction force of the belt retractor. In Figure 2 and Figure 3, the 2nd solution of a holding device for a stored head seat belt (1) is shown: A storage recess (12) is integrated into the head end of the backrest (16) of the seat. With the chin guard (2, 13) folded up, the forehead strap (1) can be pushed into the recess (12) from above and locked in place. A resilient (19) counter-pressure lever (18) is pushed back to lock it in place and provides space for the head strap, which slides into a holding slot (17) at the lowest point of the holding device. The head seat belt is firmly seated in this locking device because, in this storage position, the back of the head belt (15) also prevents it from slipping out of the holding gap. To remove the head seat belt, the driver / occupant pushes the head seat belt slightly backwards against the resistance of the resilient counter-pressure lever (18) and removes the head seat belt (1) upwards from the storage recess (12). FIG. 4 shows the third solution of a holding device for a stored head safety belt (1): FIG. 4 a shows the fixed forehead belt in a schematic view from the front. The pairs of clamps (21), which are held apart by two springs (23) and can be pressed together about a central axis (22), are attached to the front of this forehead bracket - hidden under a corresponding cover. The portions of the pairs of clamps (21) protruding over the surface (shown with solid lines in FIG. 4 a) are responsible for locking into the storage trough (12) according to FIG Pair of clamps (21) (bb indicated in Fig. 4 a) a head seat belt (1) inserted into a suitable holding slot area (24) with its layers of padding, the metal or plastic bracket, the belt strap and the pairs of clamps as the frontmost (= topmost in Fig 4 b) shown. To remove the head seat belt from this holder, the person on the head seat belt only presses one of the two pairs of clamps between thumb and finger (s) and can remove the released head seat belt upwards.
