Definitions
- the technical field of the invention relates to secure vehicle structures, provided to deform in case of impact with an external obstacle, without injuring the occupants of these vehicles. More specifically, the invention relates to a vehicle structure, whose deformation, under the effect of a lateral impact, is controlled, to prevent said structure from coming into contact with one of the occupants and not injured.
- the invention is particularly suitable for motor vehicles, whose structure is equipped with middle feet, the deformation of these feet in the middle, in case of side impact, which may lead to their intrusion into the passenger compartment, and be critical vis-à-vis occupants of said vehicle.
- the X axis corresponds to a longitudinal axis of the vehicle, the Y axis to a transverse axis of said vehicle and the Z axis to a vertical axis.
- patent US5938273 which relates to a motor vehicle structure, having two middle legs, each having a rib body, designed to deform and damp a side impact. These middle feet therefore have an exclusively damping function through a geometry intended to facilitate their deformation.
- middle feet are hollow parts defined by an outer skin and an inner liner, fixed on said outer skin by a system of folded tabs, inserted in housing of said skin.
- the center pillar tends to deform at its lower part, by folding inwardly of the passenger compartment, this folding resulting in a downward pull of the upper part of the passenger compartment. the filling, causing the instantaneous release of the legs out of their housing.
- This output is accompanied simultaneously by a displacement of the liner towards the interior of the passenger compartment, at the level of said legs, towards the occupant placed closest to said foot, while continuing its weak grout sows vertically along the skin.
- the invention aims to avoid this dangerous intrusion of the legs inwardly of the passenger compartment, to reduce the risk of injury, or even cancel, by providing a simple system for guiding the legs along the skin of the vehicle.
- the present invention relates to a secure vehicle structure, comprising on each side, on either side of the longitudinal axis, at least one substantially vertical foot, each delimited by an outer skin and an inner liner, these two elements being connected to each other in the upper part of the foot, by means of at least one attachment member of a member cooperating with at least one housing of the other element.
- the main characteristic of a vehicle structure according to the invention is that each housing is constituted by an elongated hole whose longitudinal axis is substantially vertical, the length of said hole being dimensioned so that the fastening member can slide. vertically in case of side impact.
- the foot bends at the bottom, causing a pulling force downward on the upper part of the liner relative to the skin, inducing a misalignment of these two elements.
- This sliding of the lining along the skin generally causes the exit of the fastening members of their housing, causing the spacing of the liner relative to the skin, since said bodies then abut against the skin.
- These bodies then play a spacer role between the skin of the vehicle and the occupant, making the foot dangerous for this occupant of the vehicle, placed near said foot.
- Extending the holes in a vertical direction promotes the free sliding of the lining along the skin in a substantially vertical direction, because it avoids the exit of the fastening elements of their housing, said elements being able to move the along these holes without being deflected laterally towards the occupant.
- the fastening member is integral with the liner, the hole corresponding to it being made in the outer skin.
- the structure has two fasteners in the form of two legs having substantially an L shape, the first segment is in a horizontal position and the second segment is found in a vertical position.
- the first segment is secured to the upper part of the liner, and abuts against the upper edge of the corresponding elongate hole and located on the skin, the second segment having a free end located above the first segment. .
- the two tabs are identical and are aligned in a horizontal direction.
- the length of each hole is between 2 and 12 centimeters.
- the length of each hole is between 5 and 10 centimeters.
- each hole has a rectangular contour.
- it can take other forms, the main thing is that it is lengthened in a vertical direction to ensure a rectilinear stroke of the legs along the same vertical direction.
- the invention also relates to a motor vehicle, characterized in that it has a structure according to the invention.
- the vehicle structures according to the invention have the advantage of being secured vis-à-vis the occupants of it, while maintaining a constant footprint, since the feet benefit from local amenities, by removal of matter. In addition, they have the advantage of not entailing major additional costs during the manufacture of vehicles, insofar as the structural modifications made to the feet are minor and easy to implement.
- Figure 1 is a perspective view of a central pillar belonging to a motor vehicle structure according to the state of the art, and reacting to a side impact.
- Figure 2 is a zoomed view of the upper middle leg of Figure 1 responsive to a side impact.
- Figure 3 is a zoomed view of the upper part of a middle pillar belonging to a motor vehicle structure according to the invention.
- a motor vehicle structure belonging to the state of the art has two middle feet 1, located on either side of its longitudinal axis, in approximately central position in the cockpit, and implanted in a vertical direction.
- the middle foot 1 tends to deform inwardly of said passenger compartment, folding in two at its lower part 2 in a transverse direction Y of the vehicle .
- a central foot 1 is a hollow part, conventionally delimited by an outer skin 3 and an internal lining 4 which can be made of plastic, said lining 4 being riveted to said skin 3 at the upper part of the foot 1, via two lugs 6 curved.
- Each tab 6 is substantially L-shaped, the first segment 8 of which is in the horizontal position, and the second segment 9 of which is in a vertical position, said second segment 9 having a free end 10 situated above said first segment 8. This first segment 8 is secured to the upper end 7 of the liner 4.
- the outer skin 3 of the foot 1 has two holes 11 aligned in a horizontal direction, and whose spacing corresponds to the separation distance of the two legs 6
- the first horizontal segment 8 of each lug 6 abuts against the upper edge of the hole 11 of the corresponding skin, the second segment 9 emerging on the other side of the skin 3, with respect to the lining 4.
- each lug 6 in the shape of an L presents a bend at right angles to its inner part, to distinguish two perpendicular planes generating a clean break, and a rounded elbow at its outer portion, allowing a gradual transition between the two segments 8,9, each leg 6 being in contact with the upper edge of the hole 11 corresponding thereto, through its inner elbow.
- a secured vehicle structure according to the invention differs from existing vehicle structures, in that the holes 111 of the outer skin 3 cooperating with the lugs 6 of the inner liner 4 to form the middle feet, are elongated in a vertical direction. Indeed, it is important to provide a free space under the tabs 6, when the liner 4 is attached to the outer skin 3, so that the upper portion 7 of said liner 4 can slide freely in a vertical direction along the skin 3, in the event of a lateral impact on the lower part 2 of the foot 1, without undergoing lateral displacement due to the exit of the lugs 6 from their holes 111.
- each tab 6 is in abutment against the upper edge of each hole 111, and, in the event of lateral impact at the bottom 2 of foot 1, the upper end 7 of the lining makes a vertical downward movement, the sliding lugs 6 along their respective hole 111.
- the length of the holes must be greater than 5 cm.
