Definitions
- the invention relates to an energy absorbing device for the interior of a motor vehicle having the features of the preamble of patent claim 1.
- DE 20 2004 008 985 Ul shows a relative to a vehicle door movably arranged element which can be transferred with a variety of mechanisms from a starting position to an end position.
- bellows assemblies are provided which expand when filled with air thereby providing transfer from an initial position of the movably disposed member to an end position.
- various toggle lever arrangements are disclosed in connection with a linear drive.
- the linear drive may be, for example, a preloaded spring.
- the known mechanisms for transferring the movable element from a starting position to an end position also occupy a certain space in the starting position, so that corresponding installation space must be provided behind the movable element.
- additional actuators such as gas generator or linear drive necessary, which also require additional space.
- the present invention is based on the object to provide an energy absorbing device for the interior of a motor vehicle, which is easy to manufacture and at the same time takes up little space.
- the invention is characterized by two relatively movably arranged elements, one of which is fixed to the vehicle and the other can be transferred from a starting position to an end position, wherein between the elements an actuator is arranged and a receiving device for fixing the actuator is provided.
- the receiving device is designed such that it at least partially receives the actuator.
- the actuator can be arranged at least partially within the elements.
- the elements which can be moved relative to one another may be planar elements, such as, for example, parts of the interior trim or parts of seats, headrests, cockpit, etc.
- the invention has the advantage that the relatively movably arranged elements require little space and thus can be easily integrated into a vehicle interior. On the one hand, no additional space is required on the other hand, such space-saving elements can make visually vivid and thus inconspicuously place in the interior.
- the actuator is a spring.
- other can be provided in the acting as a recording device exceptions integrable actuators, such as cylinders, small motors, piezo actuators, etc ..
- the spring may be formed, for example, as a consisting of at least one leg, at least one winding and at least one other leg or bracket spring.
- two windings may be provided, between which the bracket is arranged.
- additional legs may be provided on the sides of the windings opposite the bracket.
- the spring for example, the windings with the legs
- the bracket is supported during the pivoting movement of the other element.
- it can trigger a relative movement between the two elements.
- Such movement may also be performed by any other type of spring, such as a coil spring.
- springs as actuators, it is conceivable to set a certain amount of energy absorption via the spring force.
- the relatively movably disposed elements may absorb a certain amount of energy in the event of impact upon contact with an occupant.
- the exception acting as a receiving device may comprise a pin.
- This pin can be a separate component. But it can be formed by a one-piece design of the element. The pin can be aligned parallel to the extension direction of the element. In this case, the exception is designed as a U-shaped exception.
- the spring is arranged relative to the receiving device such that it encloses with a winding arranged in the exception pin, a particularly simple way of fastening or locking the spring is provided relative to one of the relatively movable elements arranged. It is conceivable to provide a stop which limits a movement of the spring. Thus, a targeted movement of relatively movably arranged elements can be implemented. If the movement of the relatively movably arranged elements is caused by a pivoting movement of a bracket, it is conceivable to position the stop such that the movement is stopped when the maximum distance between the two elements is reached. About the positioning of the stop and the limitation of movement of the spring can be set in a particularly simple manner, the degree of energy absorption.
- the stop may be, for example, a projection arranged on one of the elements.
- the projection like the pin, can be made as a separate component or as a projection formed integrally with the element.
- the two elements can communicate with one another via fixing elements. These fixing elements are designed so that they can be solved in a particular vehicle situation. By releasing the fixing the actuator is released. When the actuator is a preloaded spring, the movement of the preloaded spring is initiated by the release of the fixing elements. If the actuator is a motor or a piezoactuator, this can also be triggered via a signal of a control device.
- the two elements arranged so as to be movable relative to one another in an envelope. If the shell is made gas-impermeable, a vacuum can be generated in the shell, which-should the two elements move relative to each other-can be lifted. To the Generating the vacuum can be connected to the shell of a vacuum pump.
- Fig. 1 is a plan view of an energy absorbing device according to the invention
- Fig. 2 a section through an inventive
- Fig. 3 is a sectional view of the invention
- Fig. 4 is a sectional view of the invention
- Fig. 5 is a sectional view of an energy absorbing device according to the invention with three relatively movable elements
- Fig. 6 an energy absorbing device according to the invention as a door trim as well
- Fig. 7 shows an energy absorbing device according to the invention as part of a headrest.
- 1 shows an inventive energy absorbing device 1 is shown for the interior of a motor vehicle.
- an element 2 of two relatively movably arranged elements.
- the element 2 may be arranged fixed to the vehicle.
- the element 2 may also be an element which is arranged to be movable relative to the vehicle-fixed part.
- exceptions 4 are introduced.
- the exceptions 4 are U-shaped. Thus arises on the one side of the exception 4, a mandrel or pin 5.
- an actuator in the form of a spring 6 can be seen.
- the spring 6 has two legs 7, two windings 8 and a bracket 9.
- the bracket 9 is disposed between the two windings 8.
- On the outside of each winding 8 is followed by a leg 7 at. In the illustrated configuration, that is, when the legs 7 and the bracket 9 are disposed on one side of the windings, the spring 6 is biased.
- the exceptions 4 are each arranged to each other so that the arranged in the exceptions 4 pins 5 are arranged on the mutually facing sides of the exceptions 4. In other words, the open sides of the U have the exceptions 4 to each other.
- the springs 6 are arranged in the exceptions 4 so that their windings 8 surround the pin 5.
- the legs 7 are then arranged on the side of the exceptions 4, which have no pin 5.
- the bracket 9 adjoins the side of the exceptions 4, on which the pin 5 is arranged.
- a reverse arrangement is conceivable.
- a structurally very simple receiving device for the springs 6 is created.
- On the illustrated element 2 are a plurality of springs
- the springs 6 are arranged mirror-inverted to the springs 6 of the first row, that is to say that their legs 7 and bow 9 point in the opposite direction.
- the second row is followed by a third row, in which the springs are aligned in the same way as in the first row. The same applies to the subsequent fourth row compared to the second row.
- exceptions 4 provide for another exception 11.
- This exception is quadrangular in the illustrated embodiment and will be described in more detail in connection with the following figures.
- FIG. 2 shows a cross section through the embodiment just described along the line II-II in Figure 1 is shown.
- the lower plate represents the element fixed to the vehicle 2 and the upper plate represents the element 3 which can be transferred from an initial position to an end position.
- springs 6 can be seen, which are arranged between the elements 2 and 3.
- the windings 8 and the bracket 9 can be seen.
- the exceptions 4 are, however, as shown in Figure 1, at the height of the windings 8 and protrude with its pin 5 in the windings 8 of the springs 6 inside.
- In the element 3 are also exceptions to the Windings 8 provided. However, these exceptions have no pins 5, which reach into the windings 8.
- each spring 6 a projection 12 can be seen on the element 3.
- the projections 12 protrude into the quadrangular exceptions 11. Thereby, a movement of the elements 2 and 3 is prevented parallel to their extension direction.
- the square exceptions 11 allow the elements 2 and 3 to come to lie in their initial position with a minimum distance to each other.
- the projections 12 act as a stop for the bracket 9 of the springs 6. This can be seen in Figure 4, in which the energy absorbing device 1 according to the invention is shown in its final position.
- the end position is characterized in that the brackets 9 of the springs 6 have completed a pivoting movement about an unillustrated through the windings 8 of the springs 6 extending axis. They have exerted a force of the element 2 on the element 3, whereby it has carried out a movement. The movement has increased the distance between the elements 2 and 3.
- the projections 12 are provided, which constitute a limit to the above-described pivoting movement of the bracket 9.
- the movement of the bracket 9 is suppressed to a predetermined opening angle and thus defines the distance of the elements 2 and 3 in their final position.
- the inventive solution an energy absorption device 1 is created, which takes up very little space to complete. This is achieved by the actuator in the Starting position is arranged substantially in the overlap area with the elements 2 and 3. Namely, it extends with its windings 8 exclusively in the exceptions 4, so that the total height of the energy absorption device 1 from the thicknesses a and b of the elements 2 and 3, and from a distance c of the elements 2 and 3 composed to each other. This distance c corresponds in the illustrated embodiment, the thickness of the bracket 9 of the springs 6.
- the distance c in the starting position of the elements 2 and 3 are minimized to zero, so that the thickness of the energy absorbing device 1 is composed only of the thicknesses a and b of the elements 2 and 3.
- the exemplary embodiment illustrated in FIG. 3 differs from the exemplary embodiment described above in that the elements 2 and 3 are arranged in a sleeve 13.
- the shell 13 is made gas-impermeable, so that in it by means of the valve 14 and a vacuum pump, not shown, a vacuum can be established.
- the sheath 13 provides a means by which the elements 2 and 3 can be fixed in their initial position.
- FIG. 5 shows an exemplary embodiment of the receiving device 1 according to the invention, which differs from the previously described exemplary embodiments in that an additional element 3 1 is provided which is arranged relatively movable to the element 3, wherein the element 3 is in turn arranged relatively movable to the element 2.
- springs 6 are arranged, which cause a transfer from the starting position to the end position.
- Figures 6 and 7 show application examples of the energy absorbing device 1 according to the invention, it is for example conceivable to arrange this on a door 15, wherein the convertible from an initial position to an end position element 3 is a piece of door trim and the springs 6 between the element 3 and the door are arranged. Likewise, it is conceivable to form the energy-absorbing device 1 according to the invention, as shown in FIG. 7, as part of a headrest 16.
