る。BACKGROUND OF THE INVENTION Such a safety belt retractor is known from DE 34 07 378 A1. In such a safety belt winder with a tensioning device, the belt winder is supported in a radially immovable manner within the case of the safety belt winder, and the belt winder is A radially swingable blocking member is supported on the belt winding shaft on the control device side of the winding machine, and the connection position with the tooth group fixed to the case is determined by the action of the control device that reacts to the vehicle and the belt. so that the belt winding shaft is prevented from rotating upon engagement of the teeth. The tensioning device is provided on the opposite side of the case, that is, on the tensioning device side, and the tensioning device is connected to a sheave supported on the belt winding shaft via a transmission rope, and is fixedly connected to the belt winding shaft. A radially deflectable blocking member is supported on the sheave for engagement with the joint teeth, so that when the transmission line is unwound from the sheave under the action of inertia, the blocking member is attached to the joint of the belt winding shaft. It is deflected radially to engage the teeth, thereby connecting the sheave and the belt winding shaft to each other.

運動が行われない。Such a connection between the tensioning device and the belt winding machine is such that, under the action of the control device, the entire belt winding shaft, together with the restraining teeth fixed thereto, engages in the teeth formed in the end wall of the case. It cannot be used in belt winding machines where the belt winding shaft is restrained by moving in the radial direction. A belt winding machine which operates according to this restraining principle with a belt winding shaft which can be moved radially into a restraining position is known, for example, from German Patent Application No. 264
It is described in the specification of No. 6238. Now, when the tensioning device acting on the belt winding shaft is started,
The force generated by the tensioning device moves the radially movable belt winding shaft into a locked position, so that no reliable winding movement takes place during tensioning.

It is movable in the radial direction to engage the group, and the grooves of the restraining tooth group have a flexible cover in order to form a smooth outer periphery.

り軸とケースとの相互拘束が行われる。[Effect of the invention] Since the tooth grooves of the restraining tooth group of the belt winding shaft are covered, a smooth outer ring is formed, and in case of tension, the belt slides along the tooth group fixed to the case of the belt winding machine. The smooth outer periphery of the winding shaft is supported by a set of teeth fixed to the case, making it impossible to move the belt winding shaft in the radial direction until the belt winding shaft and the respective restraining teeth on the end wall of the case engage. do. Therefore, despite the restraining principle with a radially movable belt winding shaft, it is initially possible to carry out the tensioning movement by counter-rotating the belt winding shaft. It is only when a large load occurs due to the belt pull-out force acting after the belt winder is blocked that a radial movement of the belt winding shaft occurs and the teeth of the tooth set fixed to the case move against the restraining tooth set of the belt winding shaft. It pierces through the cover of the tooth groove and engages with the restraining tooth group of the belt winding shaft, whereby the belt winding shaft and the case are mutually restrained.

Instead, it is advantageous if the tooth space cover is formed from a sleeve which is fitted over the locking teeth and is made of plastic which can be broken under suitable loads. In this process, when the belt winding shaft is tensioned, the tips of the teeth on the case side slide on the cover and create a resistance force that prevents them from engaging with the restraining teeth on the belt winding shaft.
Make sure the cover has it.

Matched to the teeth between the
On the tensioning device side at the restraining position of the belt take-up roller,

According to a further embodiment of the invention, the joint tooth group and the tensioning device-side restraining tooth group are configured side by side in the axial direction, or alternatively, the tensioning device side Both the tooth groups for coupling and for restraining the belt winding shaft can be provided in one plane in the axial direction.

It passes through a notch 14 in the case end wall 13 of 0 and is supported in an outer cover 15 so as to be movable in the radial direction. On the so-called control device side 16 of the belt winder 10 there is a control device for controlling the winding spring and the vehicle of the blocking member that prevents the pull-out movement of the belt winder 10 and in reaction to the belt, and on the tensioning device side. At 17 there is a joint that connects the belt winding shaft 11 to a tensioning device (not shown). The notch 14 in the case end wall 13 has a group of teeth 18 fixed to the case.
A tooth group 19 fixed to the belt winding shaft 11 is provided in the plane of the case end wall. During a radial movement of the belt winding shaft 11, the tooth groups 18 and 19 engage with each other and prevent a further rotation of the belt winding shaft 11.

ト巻取り軸１１との連結が行われる。A sheave 20 is rotatably supported on the belt winding shaft 11, and a transmission rope 21 is wound around this sheave. This transmission line 21 is generally connected to a piston-cylinder drive to which a pressure medium is applied, and after starting the tensioning system the transmission line 21 is unwound from the sheave 20. A blocking member 22 is supported on the sheave 20 so as to be able to swing outward in the radial direction, and when the sheave 20 rotates, the blocking member 22 is deflected outward due to the inertial force acting on the blocking member, and the belt is deflected in the same plane. Since it engages with a joint tooth group 23 formed on the winding shaft 11, the sheave 20 and the belt winding shaft 11 are connected.

られている。As can be seen from FIGS. 2 and 3 of the drawings, the tooth groove 24 between the tips 25 of the restraining teeth 19 of the belt winding shaft 11 has a cover 26 . When a moving force is generated on the belt winding shaft 11 by the tensioning device during the reverse rotation of the belt winding shaft 11, the cover 26 acts against this movement, and the smooth outer periphery of the thus formed restraining tooth group prevents the case. The cover 26 is stiffened to slide over the teeth 18 of the side teeth.

拘束が行われる。The safety belt retractor according to the invention operates as follows. When the tensioning device is activated in the event of an accident, the belt winding shaft 11 is first rotated in the opposite direction during tensioning. At this time, the belt winding shaft 11 is pressed against the case-side tooth group 18 by the smooth outer periphery formed by the cover 16, so that the belt winding shaft 11 is not prevented from rotating in the opposite direction. After the tensioning movement is completed, a load is applied to the belt winder by the belt pull-out force acting on the belt winder, and this belt pull-out force is applied to the case side of the belt winding shaft 11 having the restraining tooth group 19 by the control device. This is translated into a radial movement towards the tooth group 18 and, due to the large load, the tooth 18 now breaks through the cover 26 so that on the tensioning device side 17 the tooth group 18,1
9, and thus the belt winding shaft 11 is securely restrained.
【００１５】この場合ベルト巻取り軸１１の必要な連結

A smooth outer periphery of the first restraining tooth group 19 is obtained.

The joint tooth groups 23 coupled to the take-up shaft 11 can be arranged side by side in the axial direction. However, in order to obtain a small overall axial length, it is also possible to provide two sets of teeth in one plane that act radially outwardly and radially inwardly.
