The belt safeguard is intended to make wearing of the safety belt more comfortable and safer and thus to increase the wearing rate in that it avoids troublesome pressure points on the upper body of the passenger, does not damage the clothing and reduces the risk of injury. The belt safeguard is ideally suited to retrofitting.

Description

Belt protection for seat belts

Description The invention relates to a belt protector for seat belts of vehicles.

The well-known seat belts are made of a high-strength one Belt strap, which is relatively thin, especially with automatic belts, so that it saves space - can be rolled up on the automatic roll.

This belt material can cause serious injuries in the event of an accident in the neck area, e.g. the carotid artery, by cutting the thin webbing.

Furthermore, the belt strap is on the skin in the shoulder area, in particular on the collarbone, felt to be uncomfortable because the strap on every small one Movement of the upper body on the skin and chafing through the belt edges at the same time exerts a disturbing pressure on the bone parts. Also the temperature difference the belt strap, e.g. too cold in the colder months of the year, or sticky in the summer time, is perceived as annoying on the skin.

Because of this, the seat belt is specially made by women off-the-shoulder dresses are often rejected.

The mentioned disadvantage of chafing affects itself when worn for a long time the seat belt also on the clothes. Shiny ones are created Stripes that make the garment unsightly and devalue. This too will given as a reason not to wear the seat belt.

If the belt is older and clothes are sensitive to dirt worn, dirt edges arise, which contribute to the fact that the seat belt does not is created.

All of these disadvantages are major contributory causes for the high Responsible for the proportion of passengers not wearing seat belts. The height Protective effect or chance of survival the seat belt in the event an accident has long been undisputed.

The object of the invention is to overcome the disadvantages described at the outset off and thus increase the seat belt rate. This task is carried out by a Belt protection solved as it is according to the invention by the features of the characterizing Part of claim 1 is characterized.

This is to ensure that the belt protection in the upper body area is fixed and the belt strap can slide through as desired in the belt protector. this is particularly important for the automatic belts that are now common, because the webbing straps a long way over the upper anchoring flap when putting on and taking off back on the door pillar.

Further features and expediencies of the invention emerge from the description of exemplary embodiments with reference to the figures. From the figures show: Figure 1 is a perspective view of an embodiment in a ready-to-drive representation FIG. 2 shows a perspective view of an embodiment in a stored representation Figure 3 is a sectional side view of the invention; Figure 4 is a plan view of the invention with the belt guard partially unfolded The belt strap 1 of the seat belt is attached to the lower and upper door pillar of a vehicle. Using the example of an automatic seat belt the belt strap 1 is fixed at one end to the lower door pillar or to the attachment 3 of the automatic housing 2 is connected through the lock shackle 4 and via the Deflection bracket 5 attached to the upper door pillar and ends in the automatic housing 2.

When the seat belt is put down, the belt strap 1 sags the spring preload of the automatic retractor (not shown) is relatively tight in the deflection bracket 5.

The lock shackle 4 is by a thickening 6 on the belt strap 1 at grip height held.

When putting on the seat belt, the webbing 1 is by means of the Lock shackle 4 from the automatic housing 2 against the spring force pulled over the body of the vehicle occupant. After the lock shackle has clicked into place 4 in the receiving lock 7 fastened on the inside of the seat 8 is the Seat belt functional.

The invention relates to a fabric or fur-like protective cover 9, which encloses the belt strap 1 between the lock bracket 4 and the deflection bracket 5 and held together, for example, by means of sewn-in Velcro fasteners 11a, 11b will.

A rubber band 12 sewn into the top of the protective cover 9 connects the suspension device 13, which is suspended in the deflection bracket 5 under the belt strap 1 will.

The suspension device 13 comprises a suspension bracket 15, which by means of a head rivet 16 or a screw that movably connects the clamping lug 14. the The clamping tab 14 consists of two identical halves 14a, 14b and points at the clamping point 19 has a bulge which ends in a clamping toothing. The elastic band 12 is between the two clamping bracket halves 14a, 14b by the rivet 18 on the Terminal point 19 held.

For a good alignment of the protective cover 9 and its suspension the self-centering connection between the hanging strap ensures that the strap 1 is attached to the belt strap 1 15 and the clamping lug 14. The movable head rivet 16 can be in a radius-shaped trained elongated hole 17 in the hanging bracket 15 move laterally while it is fixed in the clamping lug 14. Since the radius of curvature of the elongated hole 17 is centric is in the direction of the deflection bracket 5, there is always a centering in the direction of the deflection bracket 5 when the belt strap 1 and thus the protective cover 9 through the upper body of the occupant is moved sideways when leaning forward or backward. So that is the sideways movement of the entire protection from the clamping tab 14 always synchronized with the belt strap 1.

If the upper body is bent forward or backward, the belt strap 1 can over the hanging tab 15 and slide within the protective cover 9 while the Protective cover 9 due to its static friction, e.g. fur hair 9a, on the upper body moved along.

Prerequisite for the webbing 1 to slide smoothly in the protective cover 9 is a relatively smooth inside 10. Optionally, a feeding is possible with a smooth material, e.g. silk, is appropriate.

The difference between the protective cover 9 on the upper body and the Deflection bracket 5 is compensated for by the rubber band 12. Rubbing movements through the belt strap 1 on the upper body are thus excluded.

When you take off the automatic belt, the belt strap 1 is in the automatic housing 2 drawn in and rolled up. The thickening 6 in the belt strap 1 prevents slipping through the lock shackle 4 and pulls it into the easy-to-grip starting position for Reinstall. The protective cover 9 is also pushed upwards. That Due to the force of gravity of the suspension device 13, the rubber band 12 forms a loop and the upper edge of the protective cover 9 is supported on the passage of the deflection bracket 5. The protective cover 9 itself pushes itself together like a bellows. That’s the automatic belt including the entire protection stored without additional handles, does not bother when getting in or out, especially in two-door vehicles with rear seats, and is ready to hand to put on.

To clean the protective cover 9, the hanging tab 15 is unhooked, the protective cover 9 is opened and unfolded at the closures 11a, 11b. The protective cover 9 can be removed from the webbing 1 without tools. Should the protective cover 9 for If the washing machine is suitable, it is advisable to use a detachable one instead of the rivet 18 Connection, e.g.

Screw or clip lock to attach.
