Description

  The present invention is a safety device for a passenger compartment of an automobile, and has a trapezoidal base structure having an inner main frame and two wings protruding laterally from the inner main frame, and the two wing parts are main. The present invention relates to a safety device comprising a trapezoidal base structure that is pivotable relative to a frame and a flexible surface structure defined by a main frame and two wings. The invention further relates to a safety device arrangement in an automobile cabin.

  In automobiles, especially station wagons, effective safety measures for luggage are very important. This is necessary in particular to protect the vehicle occupant from the baggage that bounces off, for example during hazard braking or when a collision occurs when the vehicle is suddenly decelerated. A safety device known from the prior art is arranged between a passenger compartment and a loading space of an automobile and has a main frame. A flexible surface structure is stretched over the main frame. This kind of safety device, which extends in the vertical direction of the car at a predetermined installation position, allows the jumping load to be restrained to a certain extent in the forward direction, thereby preventing injury to the vehicle occupant. In contrast, this type of safety device does not provide lateral protection from the leap baggage.

  A safety device of the type mentioned at the beginning is known from (Patent Document 1). The safety device has two wings in addition to the main frame. The two wings can be deployed at the sides by pivoting about a horizontally extending axis of rotation at a predetermined installation position of the safety device in the vehicle, so that the load in the forward direction can be The total surface area of the safety device that can be used for constraints can optionally be increased. After deployment, the wings spread in a plane defined by the main frame. This safety device known from the prior art has the disadvantage of providing only limited protection from laterally splashing objects.

German Patent No. 196 05 907 B4 specification

  The problem addressed by the present invention is to provide a safety device that can better protect a vehicle occupant from a leap baggage and an arrangement structure of the safety device in a passenger compartment of an automobile.

  This problem is solved by a safety device of the type described above having the features of the features of claim 1 and the arrangement of the safety device in the vehicle compartment having the features of the features of claim 8. The dependent claims relate to advantageous developments of the invention.

  The safety device according to the invention is characterized in that each of the two wings is pivotable at least partly about a pivot axis extending in the vertical direction of the motor vehicle at a predetermined installation position of the safety device. Thus, in contrast to the prior art, the two wings are pivoted outward about a horizontal pivot and are not thereby deployed. The safety device according to the invention has a folding mechanism for each of the two wings. This folding mechanism allows the wings to pivot about a pivot axis extending in the vertical direction of the vehicle at a predetermined installation position of the safety device. In this way, the wings can be pivoted into the loading space with respect to the main frame during installation, whereby the wings can each be attached to, for example, a side panel. The safety device according to the present invention restrains a load loaded in the loading space of an automobile in a forward direction by a main frame and a part of a flexible surface structure defined by the main frame at the time of hazard braking or collision. This has the effect that it can also be suppressed laterally by the two wings and the part of the flexible surface structure defined by the wings. In this way, advantageously, it is also possible to provide vehicle occupant protection in the lateral direction from the baggage that jumps out, thereby further reducing the risk of injury to the vehicle occupant.

  The folding mechanism that allows the two wings to pivot at least partially with respect to the main frame about the vertical axis of the vehicle can be designed in a completely different way. In an advantageous embodiment, it is proposed that the two wings are made of a bendable material. Thus, by producing the wings from a bendable material, the inherent curvature of the two wings is obtained. This eliminates the need to provide corresponding hinge means in order to allow the wings to pivot relative to the main frame about the pivot axis extending in the vertical direction of the vehicle in the manner described above. In this way, it is not necessary to manufacture and stock additional hinge means and install them in the corresponding installation steps, so that the manufacturing cost of the safety device can be particularly reduced. By omitting the corresponding hinge means, the risk of wear which may possibly occur with the hinge means is further reduced. In particular, it is possible to design a trapezoidal base structure having a main frame and two wings as a one-piece component. This provides further advantages in terms of manufacturing and cost.

  In an alternative embodiment, it may be contemplated that the two wings comprise hinge means made from a flexible rigid material and designed and positioned to define two pivot axes. Here, it is possible to arrange the hinge means between the wing and the main frame so that the wing can pivot relative to the main frame. Alternatively, the wings can be divided into two parts by means of hinges. The first portion of the wing can be securely connected to the main frame. The second part may be pivotable relative to the first part by hinge means. By manufacturing the wings from a flexible rigid material, it is possible to achieve greater structural strength of the wings and thus the entire base structure. The wings can be made in particular from plastics or light metal materials. Similarly, the main frame can be made of plastic or light metal material.

  In a preferred embodiment, each of the two wings can have a securing means configured to releasably secure the wings to opposite side wall panels within the vehicle's loading space. By this means, the wing part can be fixed to the side wall panel inside the loading space after being pivoted in the direction of the loading space of the automobile with respect to the main frame. Preferably, the securing means can be configured to be assembled to and removed from the sidewall panel without the use of tools. Assembly and removal can be performed particularly easily.

  The flexible surface structure can preferably be designed as a protective net.

  The arrangement of the safety device in the passenger compartment of a motor vehicle according to the invention is designed such that the safety device is according to any one of claims 1 to 7 and the two wings are around the respective pivot axis of the two wings. The two wings are respectively attached to one of the two opposite side wall panels inside the loading space of the automobile. The arrangement according to the invention advantageously allows not only the protection of the vehicle occupant in the forward direction from the leap baggage but also the effective lateral protection.

  In a preferred embodiment, it is proposed that each of the two wings be releasably secured to one of the two side wall panels. Preferably, the two wings can be fixed to one of the two side wall panels so that they can be released without the use of tools, thereby allowing a particularly simple assembly or removal of the safety device. Become.

  Further features and advantages of the present invention will become apparent from the following description of preferred exemplary embodiments and with reference to the accompanying drawings.

1 shows a safety device for an automobile compartment designed in accordance with a preferred exemplary embodiment of the present invention. 1 shows a layout structure of a safety device in a vehicle cabin according to a preferred exemplary embodiment of the present invention. 3 shows details of the arrangement according to FIG.

  Referring to FIG. 1, a safety device 1 provided for an automobile compartment and designed according to a preferred exemplary embodiment of the present invention comprises an inner main frame 3 and a side projecting 2 from the inner main frame 3. A trapezoidal base structure 2 having two wings 4 and 5 is provided. The main frame 3 is preferably manufactured from a plastic or light metal material and in particular designed as a tube frame or a profile frame. The two wings 4, 5 are likewise designed in the form of a frame and can be manufactured from plastic or light metal material. Inside the base structure 2, the main frame 3 and the two wings 4, 5 define a flexible surface structure in the form of a stable fine mesh protective net 6. The safety device 1 can be installed between the passenger compartment and the loading space 101 (see FIG. 2) in the interior of an automobile, particularly a station wagon, and in the vertical direction (z direction) of the automobile at the predetermined installation position. Extend. Thereby, the loading space 101 is separated from the passenger compartment.

  The safety device 1 further comprises two fixing means 9,10. These fixing means 9 and 10 are attached to two ends facing each other at the upper part of the base structure 2. These fixing means 9 and 10 serve to fix the safety device 1 to the roof liner 102 of the passenger compartment. The fixing means 9, 10 can be in particular protruding and can be shaped so as to be able to engage a correspondingly shaped catch receiving part formed on the roof liner 102.

  The two side wings 4, 5 of the safety device 1 each have an integral folding mechanism. With this integrated folding mechanism, the wings 4, 5 can be pivoted at least partially relative to the main frame 3 about pivots 7, 8, respectively. The pivots 7 and 8 extend in the vertical direction (z direction) of the automobile at a predetermined installation position of the safety device 1. The folding mechanism can be designed in a completely different way. For example, it is possible to manufacture the wings 4, 5 from an elastically deformable material, thereby realizing the inherent curvature of the wings 4, 5 with respect to the main frame 3 without additional hinge means. If the two wings 4, 5 are completely formed by, for example, a tube frame or a profile frame and thus have a corresponding bending stiffness, the wings 4, 5 can each have two hinge means. . Those hinge means are arranged between the associated wings 4, 5 and the main frame 3 and are designed and positioned to define pivots 7, 8. The pivots 7, 8 extend in the vertical direction of the vehicle. Wings 4, 5 can be pivoted about pivots 7, 8. Wings 4 and 5 can be designed in two parts. In that case, the hinge means are arranged between the two parts, so that the wings 4, 5 themselves can be folded.

  With further reference to FIGS. 2 and 3, the details of the arrangement 100 of the safety device 1 in the passenger compartment of an automobile will be described in more detail below.

  During the installation of the safety device 1, the base structure 2 is fixed to the roof liner 102 of the passenger compartment between the loading space 101 of the automobile and the passenger compartment by means of the two fixing means 9, 10. The two wings 4 and 5 are pivoted with respect to the main frame 3 so as to protrude into the loading space 101 of the automobile. As can be seen from FIG. 2, the main frame 3 of the base structure 2 extends in this region over almost the entire width of the vehicle. This area is located especially behind the rear seat or rear bench seat of the car. The main frame 3 extends substantially over the entire height of the loading space 101 of the automobile in a state where a part of the protective net 6 is defined by the main frame 3. Thus, a forward barrier is formed against the leap-off load, especially during hazard braking or collisions where significant deceleration of the vehicle occurs.

  On the other hand, the two wing parts 4 and 5 have fixing means 11 and 12. The fixing means 11 and 12 are designed to be releasably fixed to one of the two side wall panels 103 and 104 facing each other inside the loading space 101. The first wing portion 4 is fixed to the first side wall panel 103 during installation. On the other hand, the second wing part 5 is fixed to the second side wall panel 104 facing the first side wall panel 103. The securing means 11, 12 can preferably be designed to be assembled to and removed from the respective side wall panels 103, 104 without the use of tools.

  The arrangement structure 100 of the safety device 1 in the passenger compartment of the automobile proposed in the present specification includes a main frame 3 and a main frame 3 that are loaded into the loading space 101 of the automobile at the time of hazard braking or collision. Can be restrained in the forward direction by the part of the protective net 6 defined by the two wings 4, 5 and the lateral direction by the part of the protective net 6 defined by the wings 4, 5 However, it has the effect that it can be suppressed. In this way, it is also possible to advantageously provide vehicle occupant protection in the lateral direction from the baggage that jumps out, so that improved protection of the vehicle occupant against injury can be realized.
