Abstract

The invention relates to a side door of a motor vehicle with an outer skin (2), a lateral sensor device that detects a critical driving situation, and an impact sensor that detects the actual impact and activates at least one airbag. In order to improve the side impact protection, it is proposed that a protective profile (6) is provided, which in a critical driving situation can be transferred from a rest position into a forwardly displaced position into the outer skin (2) before the activation of the gas bag takes place.

Description

  • The The invention relates to a side door of a motor vehicle according to the preamble of claim 1
  • From the DE 44 14 432 A1 is a side door of a motor vehicle is known which has an outer skin. In a critical driving situation, which is detected by a lateral sensor, measures are taken which improve the side impact protection in an actual impact. Thus, for example, an airbag accommodated in the side door is activated, which displaces the outer skin in an impact to the outside.
  • adversely it is that the forward displacement of the outer skin takes place only if it becomes an actual Impact comes. In addition, by this measure, the rigidity of side door can not be improved.
  • It is therefore an object of the invention to provide a side door of a motor vehicle, in which the side impact protection is improved.
  • The The object is achieved in that a protection profile is provided, which in a critical driving situation can be transferred from a rest position in a forward displaced position of the outer skin. The forward displacement of the outer skin takes place before the gas bag of the inner door is activated.
  • In a preferred embodiment the protective profile is reversible. That is, if the critical Driving situation no actual Impact follows, the protective profile can be transferred back to its rest position.
  • The Protection profile can be designed so that it is in its rest position a decorative strip on the outer skin forms.
  • alternative In addition, the protective profile in its rest position under an already existing trim strip are arranged.
  • If the protective profile is biased in its rest position, Only a small energy pulse is needed to protect the protection profile move forward position. The protection profile can be designed so that it has a triangular profile in its crash position forms. This has the advantage that the protection profile already a having rigid structure.
  • In a further embodiment The protection profile includes an external protection profile and an inner support profile, which are connected by striving. The external protection profile lies on the outer skin on, while the inner support profile in the door structure is housed. As a result, the protective profile can be moved parallel outwards become.
  • advantageously, can the mechanism of the return device in its inertia behavior during the triggering and extending the protection profiles of these be disconnected.
  • Further preferred embodiments explained below with reference to the drawing. Showing:
  • 1 a cross section through a side door with a protective profile in rest position,
  • 2 a cross section through the side door after 1 with a protective profile in its pre-displaced position,
  • 3 a second embodiment of a protective profile in the rest position,
  • 4 the protection profile after 3 in his forward position,
  • 5 a side view of a side door of a motor vehicle,
  • 6 a third embodiment of a protective profile in the rest position,
  • 7 the protection profile after 6 in his forward position,
  • 8th a fourth embodiment of the protective profile in its rest position and
  • 9 the protection profile after 8th in his forward position.
  • 1 shows a side door 1 a motor vehicle K not shown in a cross-sectional view. The side door 1 includes an outer skin 2 that the side door 1 closes to the outside. On the outer skin 2 is a hinged trim 3 , which pivot on an axis 4 is stored, attached. At the pivot axis 4 opposite end 5 the trim strip 3 is a protection profile 6 also pivotable about an axis 7 arranged.
  • The protection profile 6 is with an actuator linkage 8th connected, essentially in the side door 1 is housed.
  • The protection profile 6 Opposite is on the inside of the outer skin 2 a crash profile 9 welded, which forces on the profiles 3 and 6 with supports ( 2 ).
  • Furthermore, in the side door 1 be housed an airbag.
  • 2 shows the side door 1 with a protection profile 6 in his forward position. The 3 and 4 adjust the side door 1 schematically dar. As in particular from 4 visible, is the trim strip 3 in the advanced position of the protection profile 6 shifted upward according to arrow A direction.
  • Out 5 is the arrangement of the trim strip 3 seen. The protection profile 6 has a deflection slope 10 on, which allows the door to open in case of rescue. To achieve a pleasing appearance, the trim strip can be accessed via the side door 1 protrude.
  • The 6 and 7 show a protection profile 11 parallel to the outer skin 2 the side door 1 can be moved. This is indicated by the protective profile 11 an outer protective profile resting on the outer skin 12 on, with connecting struts 13 and 14 with an inner support profile 15 connected is.
  • The 8th and 9 show a protection profile 16 on a pivot axis 17 on the inside of the outer skin 2 is stored.
  • The Operation of the four different embodiments will be described below explained in more detail.
  • at a critical driving situation, for example in the event of a threatening side collision, that will be on the outside a vehicle door located protection profile in a laterally displaced away from the door Position transferred to to intercept the accident opponent prematurely.
  • In order to several goals are achieved at the same time. The impact energy can be reduced more evenly be, so that the maximum forces on the vehicle structure and reduce the occupants. In addition, intrusions into the vehicle be better prevented, because more deformation outside the Interior available stands.
  • It it is possible, through the protective profile, the rigidity of the construction against lateral To increase impact and to absorb more energy or to stand up to a greater severity hold.
  • At the Impact on the advanced protection profile leaves more time for the release process from door and head airbag. This allows the airbag housed in the side door softer be inflated. In addition can increase the time required for inflation be used to the volume of the gas bag in the timely to bring required size.
  • At the vorverlagerten protection profile can by means of a sensor, the actual Impact are determined, due to which the gas bag are triggered can. The protective profile is reversible designed and will triggered by a lateral sensor device.
  • The Trigger the protection profile is not yet with a simultaneous release of the Connected gas bags. This is only triggered when the crash sensor for the door is the actual Crash determines. Follows the critical driving situation no actual Impact, the protection profile is transferred back to its rest position.
  • A improved protective effect by the protective profile can already at a forward displacement of about 80 mm can be improved. The profile can be housed under a trim or in its folded or inserted position itself ornamental or protective cover.
  • For the fast Trigger the unfolding process and the later, reversible return the protection profile known measures can be used.
  • The protective profile can be made of metal, carbon or fiberglass plastics. By the protective profile, the deformation capacity of the accident opponent is first exploited. Even if the profile in the non-displaced position represents or is covered by a surface element, the element acts transversely as a profile and concentrates the impact energy in a line. Thus, a lightweight construction can be accommodated in a door to save space. The energy required for the operation is relatively low, since the protective profile is held under pretension. Likewise, the reaction time to transfer to the advanced position is very short. Thus, a strongly biased spring device is sufficient to bring the protection profile in crash position. For the reversible retrieval a very small electric motor with appropriate reduction is sufficient. An impact sensor can be fastened to the protective profile so that, in the event of an actual impact, a signal is transmitted to the gas bag accommodated in the side door, so that it can be triggered in good time. Alternatively, the conventional crash sensor may be installed in the door so as to be directly reached by the crash shock wave of the protection profiles. The protective profile can be mounted on the side door so that an unwanted return movement of the protection profile is prevented at not yet completely advanced position. This backstop can z. B. be represented by a ratchet or freewheel mechanism.
  • The inert mass the return device remains disconnected from the protective device in the ready position.
  • The retractor intervenes only when needed becomes. With mechanical blocking, for example after an accident, the return mechanism turns off to relieve the battery, giving it enough energy for warning and rescue communication to disposal stands.
