Definitions
- the invention relates to a device according to the preamble of claim 1.
- a number of options for solving this problem have become known, such as a net-like collecting element located in front of the windshield or an airbag in the transition region between the windshield and the front window that is sensor-controlled inflatable in the event of an impact.
- DE 28 14 107 A in conjunction with DE 2841 315 shows another solution principle for reducing the risk of injury when people collide with the front hood, which is based on the consideration is based on substantially mitigating the relatively hard and unyielding impact area located in the rear area of the front hood facing away from the direction of travel.
- This is brought about by a device actuated by means of an impact sensor for adjusting the front hood from a rest position into a resilient impact position which is raised in comparison therewith, ie by a so-called “active front hood”. Because the front hood during the collision detected by the impact sensor is resiliently adjusted with a person in a collision position that is raised compared to their rest position, i.e.
- This known construction is based on the idea that the hinge arrangement itself with the hinged hinge bracket in relation to the body, so that it is not necessary to provide a complex decoupling device between the hinge arrangement and the bonnet in the event of an impact.
- the invention also proceeds from this construction principle.
- the hinge support which virtually forms the base plate for the hinge arrangement, is connected in an articulated manner to the support support for the front fender at its front end section via an axis of rotation on a screw-on plate.
- the hinge bracket is locked by means of a sensor-controlled locking device with an eccentrically mounted bolt.
- an energy storage device preferably a prestressed coil spring, articulates on the hinge bracket.
- the locking device is released and the hinge bracket is released.
- this quickly swivels upward about the axis of rotation and lifts the front cover together with the hinge arrangement by a predetermined angle.
- the hinge bracket is set up by a guide in the event of a collision without pivot bearing by a limited stroke.
- the hinge support sits on two curved guide arms.
- an obliquely arranged piston-cylinder unit is provided, which is connected to the hinge bracket via a force-deflecting intermediate element.
- the invention is based on the object of designing the device described at the outset for protecting people in the event of a frontal impact on a motor vehicle in such a way that no deflection of force is necessary when the front hood is installed by means of a spring accumulator, and furthermore a very compact structure of the protective device can be achieved, able to absorb the high forces when set up.
- a device for protecting people in the event of a frontal impact on a motor vehicle which has a front hood covering the front end, which is articulated on the windshield side on both sides of the vehicle via a hinge arrangement in each case rotatably connected to the body of the front end, each consisting of a hinge bracket for the indirect body-side articulation of the hinge arrangement, which can be set up on the body of the front end, and from an energy-storing element that engages the hinge carrier Device in the form of a spring-loaded arrangement as well as a sensor-controlled holding device for an active engagement with the hinge bracket in such a way that the hinge bracket is held down in the normal state and can be released in the event of a collision by a sensor for a limited positioning movement, according to the invention in that the device can be attached to the vehicle , has essentially a rectangular housing in which at least two telescopically nested installation stages are accommodated in a linear manner, of which the first installation stage is held in a linear manner in the housing and the second installation
- the linear, guided installation of the profile body of the telescopic stand according to the invention ensures a uniform and therefore safe installation of the hinge bracket.
- the spring forces of the drive pressure springs can only act in the installation direction.
- the protective device according to the invention as a telescopic stand, it is advantageously possible to create a system which, with the smallest overall height (the closed overall height is smaller than the positioning stroke to be traversed) and a small width, is nevertheless high in the extended state Can absorb forces in the longitudinal direction.
- Embodiments of the invention are characterized in the subclaims and also result from the description of the figures.
- Fig. 1 is a first isometric view
- FIG. 2 shows the device according to FIG.
- FIG. 3 shows the device according to FIG.
- Fig. 4 shows a second in a longitudinal section
- Fig. 5 in three parts A, B, C in a cross-sectional view, the structure of the telescope set-up system according to the second embodiment, consisting of a housing (part A), a first stage guided therein (part B) and a second guided therein , inner step (figure part C),
- Fig. 8 in a longitudinal sectional view corresponding to Fig. 4 and Fig. 9 in an isometric cutout view the structure of the telescopic mounting device with pluggable
- Telescopic set-up device in the set-up state showing the use of the interior for further functional components.
- the inventive device 100 for protecting people in the event of a frontal impact on a motor vehicle is based on the principle that, in the event of a collision with the person, the front hood of the motor vehicle, including its hinge arrangement in the stop area, which is attached by a hinge arrangement in the stop area by a predetermined amount Hub is set up opposite the body of the front end.
- the device 100 initially has a housing 1, which contains the sensor-controlled components for the active installation of the front hood, and which is fastened to the body of the front end in the region of the hinge arrangements, preferably to the support bracket of the fender. Such a device is attached to both sides of the front end.
- a mounting plate 2 is accommodated in the housing 1, as will be explained in more detail later.
- a Hinged beam attached, for example articulated off-center in the manner of a seesaw (not shown).
- the associated hinge arrangement for the front hood is attached to the body in a known manner on the hinge carrier.
- the base plate can also be designed directly as the rocker supporting the hinge ( Figures 6 and 7).
- the hinge support is set up in the same way and also the hinge arrangement with the rear part of the front hood.
- the base plate forms a lid for closing the housing on the head side.
- the construction for extending the base plate 2 has two telescopic, formed by profile body set-up elements, which can be set up in the housing 1, which in the case of the first exemplary embodiment according to FIGS. 1 to 3 is designed as a box profile body with a base plate 1 c are.
- the first, outer set-up element consists of two profile bodies 3, 4 with a rectangular cross section, which are each guided in a guided manner on the two narrow ends of the housing (FIG. 1, No. 6). Outer shoulders 3 a, 4 a on these profile bodies 3, 4 in connection with stops 1 a, 1 b on the housing 1 limit the set-up stroke of the first set-up element.
- an inner rectangular profile body 5 to which the mounting plate 2 is fastened, is accommodated so that it can be raised.
- This inner profile body 5 forms the second, inner set-up element. In principle, it can also be guided in the housing 1.
- Inner shoulders 3 b, 4 b on the outer profile bodies 3, 4 in connection with outer shoulders 5 a, 5 b on the inner profile body limit the set-up stroke of the second set-up element.
- the arrangement of the profile bodies 3, 4 and 5 creates a telescopic nesting, which makes it possible to move a stroke path that is greater than the overall height when pushed together.
- a type of cleat guide 6 is provided on the housing 1 for the profile bodies 3, 4 of the outer mounting element.
- a dovetail guide 7 is formed for guiding the inner profile body 5 in the profile bodies 3, 4, for example.
- T-guides or round profile guides (“open keyhole”) are possible, and other elements can also be provided for limiting the extension movement of the two telescopic installation elements.
- three compression springs 8 are introduced in the inner profile, which are located between the The housing base plate 1 c and the base plate 2 extend and are guided in columns 9 which are attached to the base plate 1 c.
- the outer profiles 3, 4 can also receive compression spring support, e.g. increase starting power or to avoid noise. Because without compression springs, the outer profiles are in the retracted state without load (in the Z direction) and can therefore cause noise when there is play in the Z direction. Such an external compression spring is not shown in FIGS. 1-3. Without independent compression spring support, the outer profiles 3, 4 are, so to speak, "dragged" by the inner profile 5 when they are set up.
- the profiles used are preferably designed as extruded profiles, which allows easy manufacture of the device.
- the set-up plate 2 In the normal state of the set-up device, the set-up plate 2 is held down by a holding arrangement (not shown) against the force of the compression springs 8 which are then preloaded.
- the holding arrangement can be triggered by sensors (and also manually for test or inspection purposes).
- the set-up device described can be combined with a large number of different triggering methods, for example electromagnetically or pyrotechnically by means of appropriate actuators, or mechanically with a lever or Bowden cable. Accordingly, various designs are possible for the holding arrangement, the application-specific requirements also being important. In principle, those from the Roll bar technology known fixtures such as latches, ball locks, wedge slide, etc. are used.
- FIGS. 4 to 10 show a second embodiment of the two-stage telescopic stand according to the invention.
- the housing 1 (Fig. 5 A) is also box-shaped in the outer contours, but has a one-piece molded bottom 1 a. It can be mounted on the vehicle via holes 1 d (FIG. 7). In comparison to the first embodiment, however, it does not have any angular, but rather semicircular or shell-shaped inner guide contours 1 e, 1 f for the profiles 3 'or 4' of the first telescopic installation stage provided with complementary curves (FIG. 5 B). These guide contours reduce the risk of possible tilting or jamming of the profiles 3 'or 4'.
- the second telescopic installation stage in turn consists of a box-shaped profile 5 ', which is enclosed on the long sides by the wall of the housing and via a T-slot connection 10 in the profiles 3', 4 'of the first. Installation step is guided in a form-fitting manner, which ensures that the inner telescopic step is guided safely and absorbs the necessary forces in the event of an accident involving an accident person in the installed state.
- the mounting plate 2 by an eccentric articulation about the axis 11 on the inner profile 5'
- the z. B. has a front slope 5 'c, designed as a rotatable rocker, which favors the inclination of the front hood during the installation movement, and thus avoids jamming of the profiles with each other.
- the rocker also forms the lid of the installation system (Fig. 4) and serves to hold the hinge.
- the required set-up force is also achieved in the second embodiment via preloaded spring brackets 8, which are located within the profiles.
- Spring accumulators are ideally used in all stages.
- the inner profile 5 'of the second telescopic installation stage as shown in particular in FIGS. 4, 6 and 7, has two receptacles for receiving two compression springs 8, which are guided by spring guide bolts 9 fastened at the bottom 1c, and furthermore have the two Profiles 3 ', 4' of the first telescopic installation stage each have a receptacle for a further compression spring 8, which is also guided by a spring guide pin 9 fastened on the bottom.
- the stages are extended simultaneously and the front hood experiences maximum acceleration to achieve the required installation times.
- the advantage of this arrangement also lies in the fact that the extension behavior initially behaves in one step (FIG. 6 A) and the front hood, which is thereby sufficiently accelerated, supports the setting up of the second step into the end position (FIG. 6 B).
- corresponding shoulders / stops are provided on the housing 1 and on the profiles (1 a with 3 'a and 1 b with 4' a for the first set-up stage and 3 'b with 5 'a and 4' b with 5 'b for the second set-up stage).
- plug-in stops 1 a, 1 b; 5'a, 5'b used to put on simple
