Belt separator

Description;

The innovation concerns a belt separator for seat belts, as used in automobiles and the like. In particular, the innovation concerns a Belt cutting device with a holder, which can be fixed to a seat belt, for a cutting device which has a cutting blade fixed on a handle

'Belt cutting devices of this type are known. Example

f, DE-OS 32 17 368 discloses a container for

I wearing on a motor vehicle seat belt for one

ί approximately rectangular holder with cutting blade. This container

ί ter has a pocket-shaped, upwardly open receptacle

§ for the cutting device. On the back of the loading

In the holder, there are tabs that go along with the

ir

The rear wall of the container delimits a passage extending from the bottom to the top of the container. The j mutual adaptation of container and cutting device | consists only in the fact that a locking connection is provided | hen that the accidental falling out of the cutting | direction from the container prevented. The well-known Ein I direction is comparatively large and voluminous. J

FIG. 8 shows a further embodiment of a belt severing device according to the invention, wherein the handle is fixed via spot welds within the groove *

FIG. 1 shows schematically an unused seat belt device for a motor vehicle. At the upper end

^ a door pillar 1 is a deflection eye 2 pivotably attached, through which a seat belt 3 is guided. At the lower end of the door pillar 1 there is a - not shown - belt winding device. The belt section located outside of this winder is first guided along the door pillar 1, then runs through the deflection eye 2 on the door pillar 1 and then through another eyelet on a lock tongue 4 and ends at a - not shown - fitting adjacent to the seat wall. When the lock tongue 4 is pulled, a corresponding length of the wound strap section is released, and the result is the two parts of the shoulder belt and the lap belt. For this purpose the safety belt must be used 3 can run freely through the lock tongue. In order to still use the lock tongue when the seat belt device is not in use 4 to be held in an easily accessible position - about shoulder height, adjacent to the side wall of the vehicle, a lock tongue stop 5 is available.

FIG. 2 shows a belt separating device according to the invention on a seat belt 203 approximately to scale. Essentially, this belt separator is in Fora a U-shaped bracket 205 formed, with the lower Leg 206 and the upper leg 207, which join together via the rounded back 208

are. Stand from the inner surface of the lower leg 206 Ribs 209 running parallel to the back 208 inward, which press against the underside of the belt 203. Of the lower leg 206 preferably has a shorter length than the upper leg 207 provided with the groove 213, and the end section 211 of this shorter leg 206 is bevelled to facilitate the insertion of the belt *

The groove width can, for example, be approximately 2/5 to 4/5 of the width of the upper leg 207. The length of the groove is less than the length of the upper leg 207, the groove 213 being on the one facing the back 208 distant narrow side of the upper leg 207 begins. The groove depth is less than the thickness of the top one Leg 207 · For example, the depth of the groove can be 2/5 to 2/3 of the thickness of the upper leg 207.

The groove flanks 214 are inclined so that the groove 213 widens in the direction of the groove base. As shown, the groove 213 has an open narrow side 215 and a closed narrow side 216. In the field of open narrow side 215, a small transverse depression 218 can be cut out in the groove base. In connection to the closed narrow side 216 is cut out further material on the upper leg 207 so that a groove 213 The result is an open cavity 217 for receiving a blade 222 of a cutting device. This cavity 217 is indicated schematically in Figure 3 with dashed lines. This cavity 217 has a small, only to accommodate the cutting blade 222 there is sufficient "clear" height, so that also in this area uninterrupted Sections of the inside and the outside of the upper leg 207 with sufficient wall thickness remain to

an all-round protected accommodation of the * blade 222 in to ensure this cavity 217.

The cutting device 220 provided as a further component of the belt tube hearing device according to the invention consists of a handle 221 and a blade 222 tied to it. Length and width of the handle 221 are adapted to the length and the width of the groove 213, so that this handle 221 in form of a slide in the groove 213 on (\ pushed and fixed there. The longitudinal side surfaces of the grip 221 extend at adapted Inclination so that the inclined groove flanks 214 do not allow the grip 221 to be removed essentially perpendicularly out of the groove 213. A small projection 223 - shown in broken lines in FIG 218 can engage in the groove base when the handle 221 is completely pushed into the groove 213. This secures the handle 221 against unintentional displacement out of the groove 213. The height or thickness of the handle 221 can exceed the depth of the groove, so that the Outside of the handle piece 221 pushed into the groove 213 protrudes beyond the outside of the upper leg 207. Preferably w However, the height or thickness of the handle 221 is selected to be equal to the depth of the groove 213, so that the handle 221 in its entirety does not protrude beyond the contour of the U-shaped bracket when the cutting device 220 is fully inserted into the groove 213.

Preferably, at least a portion of the outside of the handle 221, in particular in that to the blade 222 adjacent end portion, a raised corrugation 224 is formed in order to slide out the handle if necessary 221 from the groove 215 to facilitate. The handle
