Definitions
- the invention relates to a belt retractor with a belt tensioner and a force limiting device, wherein the belt tensioner has a rotatably mounted and a belt spool associated pinion, a drive unit and a movable by the drive unit, elongate force transmission element, which is at least partially mounted in a pipe section and with the pinion in Intervention can be brought to rotate the pinion in a tightening direction.
- Belt retractors usually have a belt tensioner, which can counteract belt slack of the seat belt and a film spool effect of wound on the belt reel seat belt.
- a belt tensioner comprises, for example, a rotatably mounted pinion coupled to the belt spool, a drive unit and a power transmission element moved by the drive unit, which is mounted at least partially in a pipe section, wherein the pipe section is usually formed curved for reasons of space.
- the force transmission element is displaced by, for example, the pyrotechnic drive unit in the pipe section or partially driven out of it.
- the force transmission element comes into engagement with the pinion and causes in a further movement, a rotation of the pinion and thus coupled to the pinion belt spool in a tightening direction.
- the power transmission member is configured so that the power transmission member is in engagement with the pinion in the position which the pinion takes after rotation by the power transmission member.
- the object of the invention is to provide a belt retractor with a belt tensioner and a force limiting device in which the force limiting device is not affected by the belt tensioner.
- a belt retractor with a belt tensioner and a force limiting device wherein the belt tensioner has a rotatably mounted and a belt spool associated pinion, a drive unit and a movable by the drive unit, elongate force transmission element, which is at least partially stored in a pipe section and with the pinion is engageable to rotate the pinion in a tightening direction, wherein the force transmission element has a bent portion which is provided at the rear end of the power transmission element in the tensioning direction and which is pressure stable in the longitudinal direction of the power transmission element but in a direction perpendicular to the longitudinal direction bendable is formed.
- the invention is based on the idea of designing the section of the force transmission element which is forced back into the pipe section or into the curved pipe section in the event of a force limitation, such that the latter during the tightening process by the drive unit to the force transmission element acting compressive force loss-free as possible to the pinion can transfer, so it is very pressure stable, but can be bent with a small force, so that the force transmission element can be pushed back into the pipe section with little resistance or deformed during insertion and adapted to the course of the pipe section can.
- the bending portion is thus formed so soft that it opposes only a small resistance when pushed back into the pipe section of a bending deformation. As a result, there is no or only a slight influence on the force limiting operation by the belt tensioner.
- the bending section has at least one circumferential constriction in the circumferential direction. Due to the smaller diameter, the bending stiffness at the constriction is significantly reduced, so that it effectively acts as a joint that divides the bending section into a plurality of mutually movable sections.
- the diameter of the constrictions is chosen so that a sufficient transmission of the pressure force is possible.
- the radial depth and the number and position of the constrictions can be arbitrarily adjusted depending on the desired bending stiffness.
- the constrictions are arranged, for example, at regular intervals and / or each have the same radial depth, whereby the bending section over the entire length has a constant flexibility.
- the constrictions can also form an elongated area of smaller diameter viewed in the longitudinal direction.
- This area has a low bending stiffness due to the smaller diameter.
- this area has a larger clearance in the pipe section through the smaller diameter, so that the power transmission element can be moved easily in the pipe section.
- this area can provide a damping function for the belt tensioner to prevent a too rapid increase in the tensioning force.
- this area can be compressed, whereby it shortens to a slight extent. As a result of this shortening, the diameter of this region expands to a maximum extent up to the diameter of the remaining force-transmitting element or to the diameter of the tube section.
- This shortening of this section provides cushioning at the beginning of the tightening process, thereby increasing the tensioning force more slowly.
- This Range is preferably dimensioned so that a compression of the area can take place by the compressive force occurring during the tightening process.
- the pressure force transmitted by the pinion during the subsequent force limitation is substantially lower, so that no compression of the region occurs when the force transmission element is pushed back.
- the cross section is reduced in sections, in order to increase the flexibility and thus to reduce the flexural rigidity, but at the same time to ensure sufficient compressive rigidity. It is also conceivable, for example, that the force transmission element has grooves extending in the longitudinal direction.
- the grooves may extend over the entire length of the power transmission element, whereby the power transmission element can be made much easier.
- the force transmission element can thus be produced, for example, by the extrusion process.
- the grooves are provided only in the bending section in order not to influence the rigidity in the rest of the force transmission element.
- the force transmission element may extend in the radial direction through the force transmission element.
- the force transmission element can be compressed perpendicular to the longitudinal direction. This allows for a cross-sectional reduction, by which the power transmission element, as already explained, can be easily pushed back into the pipe section.
- the force transmission element has a longitudinally extending cavity which extends at least through the entire bending section. But it is also conceivable that this cavity extends through the entire force limiting element.
- All embodiments in which a reduction of the cross section of the force transmission element over a longitudinally larger section takes place also have the advantage that they oppose the pinion with a rotation opposite to the tightening a lower resistance.
- the passage between pinion and pipe section is usually chosen smaller than the diameter of the power transmission element.
- the force transmission element has a cavity which is filled with a preferably pressure-resistant core.
- the force limiting element can be made of a soft, in particular a flexible material.
- the transmission of the pressure forces takes place through the pressure-resistant core.
- the core is made of a harder material than the power transmission element.
- the power transmission element is made of a softer material into which the pinion can dig during the tightening process.
- the core can be made of a much harder material because the pinion does not have to dig into it. Between bending section and the rest of the power transmission element can also be provided, for example, at least one predetermined breaking point.
- the predetermined breaking point is preferably arranged so that it is pushed past the pinion during a tightening process.
- the power transmission element is separated during the tightening process at the predetermined breaking point, so that the region separated from the force transmission element by the predetermined breaking point remains in front of the pinion in the subsequent force limiting operation and does not have to be pushed back in the direction of the pipe section.
- the power transmission element can for example also consist of several sub-elements which are flexibly coupled together. Since these elements only need to transmit a compressive force, it is not necessary to connect them firmly together. It is only necessary that they can transmit a compressive force. These can thus rest against each other without a firm connection in the pipe section.
- the sub-elements may be partially spaced balls, for example.
- the rear end of the power transmission element is widened in a cone shape.
- a seal of the force transmission element against the pipe section or to the drive unit is required in order to prevent the gas from flowing past the force transmission element, so that a sufficient pressure build-up is possible.
- a ball or other suitable sealing element is provided behind the power transmission element.
- this sealing element is replaced by a cone-shaped widening of the force transmission element, so that no additional component is required for sealing. The widening is designed so that the force transmission element rests circumferentially on the inner wall of the pipe section and thus completely seals the pipe section. Due to the cone-shaped widening, the seal is automatically pressed against the pipe wall when the pressure in the pipe section increases, so that sufficient tightness is ensured even with increasing pressure.
- FIG. 1 is an exploded view of a belt retractor according to the invention
- FIG. 1 is a sectional view of the assembled belt retractor of FIG. 1
- FIG. 3 is a schematic partial section of the belt tensioner from the belt retractor of Figure 1, and
- FIG. 1 shows the essential components of a belt retractor 10 with a pyrotechnically driven belt tensioner 16.
- FIG. 2 shows the belt retractor in the assembled state.
- the belt retractor 10 has a frame 12 on which a belt spool 14 is rotatably mounted, on which a seat belt can be wound up. Furthermore, the belt retractor 10 has a force limiting device, which is not shown here in detail.
- the belt tensioner 16 of the belt retractor 10 has a pyrotechnic drive unit 18, a tensioner tube 20 with a bent pipe section 21, a in Tensioner tube 20 arranged power transmission element 22 and a pinion 24 which is coupled to the belt reel 14, on.
- the components of the belt tensioner 16 are arranged together in a tensioner housing 26.
- the roll-up mechanism 28 of the belt retractor 10 is shown in FIG. This is for the function of the belt tensioner 16 and the force limiting device is not important, so this will not be explained in detail.
- the belt tensioner 16 is shown in Figure 3 in a simplified form before a tightening process to illustrate the general operation of such a belt tensioner 16.
- the pyrotechnic drive unit 18 is activated, whereby it generates an overpressure in the tensioner tube 20.
- the force transmission element 22 is pressurized in the tensioner tube 20 and moved in a tensioning direction S away from the drive unit 18, wherein the force transmission element 22 engages with the pinion 24.
- the pinion 24 is forcibly rotated by the force transmission element 22 in a direction of rotation D.
- the coupled with the pinion 24 belt reel 14 is thereby rotated with this, wherein the seat belt is wound on the belt reel 14, so a belt tightening takes place.
- Such a belt tensioner is known from DE 10 2006 031 369.
- the power transmission element 22 may have a suitable geometry in which the pinion 24 can engage, for example a rack geometry. But it is also conceivable that the force transmission element 22 is made of a softer material than the pinion 24 and this digs when moving the power transmission element 22 in the surface of the power transmission element 22.
- a limited rotation of the belt reel 14 counter to the direction of rotation D is made possible to prevent excessive force acting on the vehicle occupant forces.
- the force transmission element 22 is designed so that this is still in engagement with the pinion 24 after completion of the tightening process, that is not completely pushed past this.
- the force transmission element 22 is therefore engaged by the pinion engaging with the force transmission element 22 24 moves against the tightening direction S and thereby pushed back into the tensioner tube 20 and the pipe section 21.
- the pipe section 21 is bent or curved for reasons of space, not only is it necessary to overcome the frictional forces of the force transmission element 22 in the tensioner tube 20.
- the power transmission element 22 must be bent to match the shape of the pipe section 21. The work required for this, however, acts as an additional resistance which acts on the belt reel 14 via the pinion 24 and influences the mode of operation of the force limiting device and thus the belt webbing extension. In other words, not only the resistance of the force limiting device must be overcome for a force limitation, so a limited Gurtbandauszug, but also the resistance of the belt tensioner, so the power transmission element 22 in the tensioner tube 20th
- the force-transmitting element 22 is flexible in a bending section 30, which substantially corresponds to the region of the force transmission element 22 which is pushed back into the bent tube section 21. That is, the force transmission element is formed pressure-stable in this area, so that it can transmit the force caused by the drive unit 18 tensioning force on the pinion 24.
- the force transmission element 22 is designed to be flexible in this bending section 30, so that the required bending work in order to adapt the bending section 30 to the shape of the pipe section 21 is possible to a small extent.
- the bending portion is thus formed on the pyrotechnic drive unit 18 side facing.
- FIG. 4 a) and b A first embodiment of such a power transmission element 22 is shown in Figures 4 a) and b).
- a constriction 32 is provided, on which the diameter of the force transmission element 22 is significantly reduced in the circumferential direction. Due to the smaller diameter, the force transmission element 22 in this area has a lower flexural rigidity.
- the constriction 32 thus acts as a kind of joint around which the bending portion 30 can be bent.
- FIGS. 5 to 12 a) and b) show various embodiments of force transmission elements 22 with constrictions 32. These embodiments all have in common a solid, continuous core, which provides sufficient compressive stiffness of the power transmission element.
- FIGS. 5 a) and b), 6 a) and b) and 7 a) and b) differ from the embodiment shown in FIGS. 4 a) and b) only in terms of number, spacing and depth the constrictions 32.
- Figures 5 a) and b) of the bending portion 30 is divided by two constrictions 32 into a plurality of mutually movable sections 34.
- Figure 6 a) and b) two constrictions are also provided, which have a different depth. By reducing the depth of the constriction, the flexural rigidity is increased. By a different depth of the constrictions 32 is thus possible to a regional adaptation of the flexural rigidity, for example, to the course of the pipe section 21.
- FIGS. 5 a) and b), 6 a) and b) and 7 a) and b) differ from the embodiment shown in FIGS. 4 a) and b) only in terms of number, spacing and depth the constrictions 32.
- the bending section 30 is divided by several constrictions 32 into subsections 34 of different lengths, which likewise results in an adaptation of the bending stiffness.
- the constrictions 32 are arranged so close to one another that they effectively form a Christmas tree profile which enables a particularly flexible construction of the bending section 30.
- the constriction 32 is formed as an elongated region 36, in which the diameter of the force transmission element 22 is reduced over a relatively long range. Due to the smaller diameter, the flexural rigidity of this region 36 is less than that of the force transmission element 22. In addition, this area has a larger clearance in the tightening tube 20 due to the smaller diameter, so that a simpler movement of this region 36 in the tensioner tube 20 and in particular in the tube section 21 is possible.
- a damping of the tightening effect and thus a slower increase in the tensioning force can also be effected via this region 36.
- the elongated portion 36 With a sudden increase in pressure on the drive unit 18 facing end 38 of the power transmission element 22, the elongated portion 36 is first compressed in the longitudinal direction and thereby widened until it has assumed the diameter of the remaining force transmission element 22 and rests against the inner wall of the tensioner tube 20. By this shortening of the force transmission element 22, a too rapid increase in the tensioning force is prevented.
- This elongate region 36 is preferably designed so that a reversible compression can take place due to the sudden rise in pressure during a tightening process. However, pushing back the force applied to the force transmission element 22 by a force applied to the force transmission element 22 by the force transmission element 22 into the tensioner tube 20 is not sufficient to compress the elongate region 36.
- FIGS. 11 a) and b) substantially corresponds to the embodiment shown in FIGS. 10 a) and b). Between the region 36 with a reduced diameter and the remaining bending section 30, only a constriction 32 is additionally arranged here.
- FIGS. 12 a) and b) has, in addition to the constriction 32, a longitudinally extending cavity 40, which extends here essentially through the entire bending section 30. Due to the reduced cross-section, on the one hand, the flexural rigidity of the bending section 30 is reduced. In addition, the bending portion 30 can be compressed perpendicular to the longitudinal direction, so that in addition a mobility or deformability of the bending portion 30 is possible.
- the cavity 40 extends through the entire force transmission element 22.
- a core 42 are inserted, as for example in the Embodiment in Figures 14 a) and b) is shown.
- This core may for example be made of a more stable material, so that it can transmit a greater compressive force. Due to the smaller diameter of this is still very flexible, so that the force transmission element 22 can bend in particular in the bending section 30 with little resistance.
- the force transmission element in the bending section 30 has a smaller diameter to the flexural rigidity and a sheath 44 of a softer material or a flexible material is provided, as shown for example in Figures 15 a) and b).
- the transition between sheath 44 and power transmission element additionally forms a constriction 32 here.
- Such a two-part power transmission element 22, in particular with an outer softer material, can be produced, for example, in a two-component injection molding process from plastic.
- FIGS. 16 a) and b) and 17 a) and b) have grooves 46 extending in the longitudinal direction, which also serve to reduce the cross-section and thus reduce the flexural rigidity.
- the grooves 46 here extend over the entire length of the force transmission element 22.
- the embodiment shown in FIGS. 16 a) and b) differs from the embodiment shown in FIGS. 17 a) and b only in that flat end regions 48 are provided. provide a stable contact surface for transmitting the compressive force.
- the grooves 46 can also, as shown in Figure 18 a) and b) and 19 a) and b), be provided only on the bending portion 30.
- the grooves 46 extend in a radial direction through the force transmission element 22, whereby the bending piece is divided into a plurality of longitudinally extending webs 50. Due to the webs 50, which can be bent individually, a particularly high flexibility is achieved.
- the power transmission element can also be covered with a wire mesh 52, as shown for example in Figures 20 a) and b).
- a wire mesh 52 is particularly flexible, wherein the compressive force is transmitted through the core 42 provided in the wire mesh 52.
- the force transmission element 22 consists of several flexibly coupled to each other sub-elements 54, 56, 58, as shown for example in Figures 21 a) and b) to 23 a) and b).
- the sub-elements 54, 56, 58 may consist of different materials.
- the sub-elements 56 balls that abut each other.
- ball 56 and cylindrical sections 54 alternate, wherein a very flexible coupling of the cylindrical sections 54 and thus of the force transmission element 22 is achieved by the ball 56.
- Figures 23 a) and b) only cylindrical portions 54, 58 sections are provided, wherein the cylindrical portions 58 are made of a flexible material having a low bending stiffness.
- an additional sealing element is provided between the force transmission element 22 and the drive unit 18, which is formed, for example, by a sealing ball 60.
- the rear end 38 of the power transmission element 22 may be formed such that it forms a receptacle 62 for this sealing element, as shown for example in Figures 24 a) and b).
- this sealing element is replaced by a conical expansion 64 of the rear end 38 of the force transmission element 22, as shown in Figures 25 a) and b). With an increasing pressure, this conical expansion 64 is pressed against the inner wall of the tensioner tube 20, whereby the sealing effect is further enhanced.
- the embodiment shown in Figures 26 a) and b) combines several elements of the embodiments described above. This embodiment is based on the form described in Fig. 4 a) and b) together with elements of Fig. 19 a) and b).
- the force transmission element 22 also has a bending section 30 and a constriction 32 in this exemplary embodiment.
- By two outgoing from the front, perpendicularly intersecting and extending in the longitudinal grooves 46 four longitudinally extending webs 50 are formed. Each two opposing webs are connected by short connecting webs 66 and 68 with each other.
- the connecting webs 66 and 68 extend at a distance from the constriction 32 and in the immediate vicinity of the grooves 46.
- the two connecting webs 66 and the two connecting webs 68 are also offset from each other in the axial direction.
- the connecting webs 66 and 68 and the constriction are additionally as Sollg. Demand fractures designed. During assembly, during the tightening process and / or when pushing back the force transmission element, these connection points can break open, so that the force transmission element then consists of five individual elements.
