Abstract

The invention relates to a novel retractor device (1) for a safety belt (27) comprising a cylindrical housing (2) that is provided with a longitudinal slot (28). A rotatably mounted spindle (7) is provided inside said housing, and the belt is wound around the spindle, whereby the spindle (7) is mounted via both of its ends inside the housing (2) in a manner that permits it to rotate. In addition, a spiral spring (24) is provided, which encircles the spindle (7) and which, on one side, is fastened to an end area of the spindle (7) and, on the other side, is fastened to the inner wall of the housing (2).

Description

Retractor for a safety belt

The invention relates to a retractor for a safety belt according to the preamble of claim 1.

From US-A-4,858,551 a retractor for a safety belt is known which is provided with a reflective paint or other luminescent material and wound on a spindle. The spindle is rotatably mounted in a cylindrical designed as a pot-shaped housing, wherein above a rotatable cover is provided with an eccentrically arranged knob. On the other hand, the spindle is provided at the top with a square, which is embedded in a four-sided receptacle of the lid, so that the spindle with the knob can be turned. The housing has a flat magnets on the outside. Also, the reflector strip at its free end a flat magnet, so that the housing and the drawn out of the housing reflective tape can be attached to the body of a car around. A detent or even a bias voltage of the tape is not provided. In addition, the tape must be manually rewound.

The present invention now has for its object to provide a retractor for a safety belt, which automatically wound up again, and a constant bias voltage on the guard band is applied.

This object is achieved by a seat belt retractor having the features of patent claim 1.

A big advantage of the inventive retractor is that the drawn tape is automatically rewound when releasing its free end. In addition, the band with increasing length is more withdrawn, resulting in a safe winding. Another advantage is the handy form and the compact design of the retractor. Further advantages of the invention follow from the dependent claims and from the following description in which the invention with reference to an embodiment shown in the schematic drawings embodiment will be explained in more detail ER. It shows:

Fig. 1 is a roll-up device in longitudinal section;

Fig. 2 is a cross section along the line AA in Figure 1,

Fig. 3 shows the retractor of Figure 1 in exploded view;

Fig. 4 is a first perspective view of the housing, and

Fig. 5 is a second perspective view of the housing.

In the figures, the same reference numerals have been used for the same elements and initial explanations relate to all figures, unless explicitly stated otherwise.

In figure 1, a retractor 1 for a safety belt (not shown here) is shown, consisting of a circular cylindrical housing 2 is arranged with top and bottom covers can be completed 3 and 4. FIG. This lid 3 and 4 can for example have a peripheral outwardly projecting annular bead, which engage in an annular groove on the inner wall of the housing 2, so that they form a snap closure. The housing 2 is divided by a circular disc 5 having a central hole. 6 In the housing 2, a spindle 7 with an axially projecting circular cylindrical cam 8 is provided, which is rotatably mounted in a circular cylindrical recess 9 of the lower cap 4 and 6 are in the central hole of the circular disc. 5 At the other end portion 12 of the spindle 7 is an axial ausgerichetete outer teeth 13 is provided, which engage in three configured as gears of planet gears 14 (see Figure 2). These gears 14 are in turn provided on the underside with a circular cam 16, which are rotatably mounted in corresponding recesses 17th The gears 14 are also rotatably mounted with internal teeth 19 in a hollow disc 18th On the opposite side 18, the hollow disc to an axis 21, which is rotatably mounted in a circular recess 22 of the top lid. 3 On this axle 21 is also a flat spiral spring 24 is fixed (see Figure 3) which is connected at its outer end to the inner wall of the housing. 2 This can be done for example with an L-shaped geboge- NEN or cranked end. On the spindle 7 which is fixed one end of the safety belt and wound the tape thereon.

2 shows a cross section along the line AA in Figure 1 by the planetary gear 26 is shown, which consists of the spindle 7 with its outer toothing 13 as a sun gear, the planet wheels 14 and of the hollow plate 18, with its internal toothing 19th serving as a guard band reflector strip 27 is indicated also composed in conventional manner of a fabric tape with a coating of reflective material, and is fixed on the spindle. 7

As will now be seen in Figure 3, has the coil spring 24 a few turns, which is why the planetary gear 26 is provided. Thereby, a larger ratio between the rotation of the coil spring 24 and the spindle 7 is in fact achieved, resulting in a much greater length of reflective tape on the spindle 7 can be wound than the length of the coil spring 24. The transmission ratio between the maximum number of turns of the coil spring 24 and the number of rotations of the spindle 7 is in this case matched to the length of reflector tape 27th It will be appreciated that there has been the more unwound strip, the greater the tension of the coil spring 24 is on the tape 27th Thus, any length of reflector tape advertising withdrawn from the housing 2 to 27, which is always tensioned. The drawn tape 27 is further drawn automatically into the casing 2 when the ribbon end is released.

In Figures 4 and 5, the housing 2 is shown in a perspective view from two different directions. The emerging from a slot 28 free strap end is provided with a T-shaped fastening means 30 which prevents a complete retraction of the reflector strip 27 in the housing. 2 The housing 2 is a box-shaped holder 31 is mounted with a slot 32 into which the fastening means can be inserted 30 (see Fig. 4). Thus, the tape 27 may comprise a complete object, for example a cardboard box or the like which is to be transported on a bicycle. You could also place around the belly of a biker or a hiker reflector strip 27, so that it is more visible in the dark from the oncoming traffic. In practice, the housing 2 has the size of a film cassette for a camera and it will allow you take with you.

It is obvious to the skilled person that other types can be used by fasteners. For example, one could provide a Velcro strip instead of the T-shaped fastening means 30, wherein the tape end is designed substantially thicker by doubling or tripling, in order to prevent that the tape is completely drawn into the housing 2 27th On the housing 2, a Velcro strip may be provided then also, so that a Velcro connection between the band 27 and the housing 2 is molded. The maximum pulling force of the coil spring 24 has to be substantially less than the force that is required to solve the Velcro connection. Also, magnetic stripe could be used as fastening means. In a further embodiment, the coil spring 24 could be mounted with a slipping clutch on the axle 21, so that an even greater length of reflector tape 27 can be wound. In such a case, not all reflective tape, but 27 is drawn back into the housing 2 so that the spindle 7 rotated by hand must be to wind all band 27th On the other hand, a tightly wound spiral flat spring 24 may be provided, as they are provide in mechanical alarm clocks, wherein the diameter of the wound helical spring 24 to that of the spindle to correspond. 7
