Definitions
- Energy absorbing device in the event of an impact for a motor vehicle seat, seat and vehicle comprising the device
- the invention relates to a device for absorbing energy in the event of an impact, in particular for a motor vehicle seat.
- the invention further relates to a seat and a vehicle comprising the energy absorbing device.
- Such a device is intended to reduce the stresses experienced by the occupant of the vehicle sitting on the seat by gradually absorbing the kinetic energy to which his body is subjected.
- the invention is more particularly intended for the absorption of energy in the event of a rear impact, but is also applicable to an impact before or even to other types of impact.
- the documents DE-196 13 506 and DE-198 07 581 each describe an energy absorption device of the aforementioned type comprising a first element substantially in the form of a plate (shaped) having a hole and a second element inserted in the hole, said first element comprising a succession of cuts succeeding one another in a direction of deformation and defining between them a succession of bridges extending in a direction of elongation transverse to the direction of deformation, said cutouts each presenting a length in the direction of elongation.
- the invention aims to improve the energy absorption provided by such a device.
- said length strictly increases from one cut to the next as a function of 1 'distance of the bridges relative to the second element and the bridges generally have a concavity facing the second element.
- the length reduces the influence of the friction (usually called sweeping) of a broken bridge on the edge of the cuts on the resistant force opposed by the device, which reduces the variations and uncertainties concerning the opposite resisting force by the device.
- the growth of the length reduces the frictional force and the concave shape prevents the broken bridges from bending. Since the resisting force is better controlled and more constant, it can be adjusted to the biomechanical strength characteristics of the human body to increase the energy absorption without causing damage to the occupant of the seat.
- each of the bridges advantageously has a substantially circular arc shape of substantially constant width over most of its length with a concavity facing the second element.
- the bridges are essentially stressed in stretching and only slightly in shear.
- the variations of the resistant force opposed by the device during the shock are thus further reduced.
- the ratio between the radius of curvature and the length of the bridges is advantageously between 0.75 and 4.
- the difference in length between two successive cuts is advantageously between 0.25 millimeters and 2 millimeters.
- the number of bridges is advantageously between 3 and 8.
- the various bridges of the succession advantageously have in the direction of deformation substantially the same width.
- the resisting force opposed by each of the bridges is substantially constant and as the broken bridges do not substantially oppose the resisting force, the resistive force of the device is substantially constant.
- the second element advantageously comes into contact with the bridges along a substantially flat (blunt) surface.
- the bridges are more likely to be stressed in stretching and breaking at their ends than at the point of contact with the second element.
- the constancy of the resistant force is thus further increased.
- the second element advantageously has a circular section.
- the cuts are advantageously delimited in the direction of deformation by the bridges and in the direction of elongation of the substantially rectilinear longitudinal edges and in alignment with each other.
- the rupture zone of the bridges is thus better controlled and the phenomenon of friction is further reduced.
- the first element is advantageously constituted by a laminated plate whose rolling direction is substantially parallel to the direction of elongation.
- the first element is stretched in a direction in which it has the best properties of mechanical strength.
- the energy absorbing device advantageously comprises two successions of cuts succeeding one another in the direction of deformation and each defining a succession of bridges between them, on either side of the hole.
- the device is capable of absorbing energy in the event of a shock in both directions, in particular in the event of a rear impact and in the event of a front impact.
- the invention further relates to a seat.
- the seat advantageously comprises, in addition to said energy absorption device, a seat structure, and a backrest structure, and the seat advantageously has the following characteristics:
- the first element is fixed on one of the seat structure and the backrest structure, and the first element is held on the other between the seat structure and the backrest structure via a articulation in rotation, and
- the second element is integral with the other one of the seat structure and the backrest structure.
- the invention further relates to a vehicle.
- the vehicle comprises, advantageously in addition to said energy absorption device, a frame and a seat comprising a fixing base.
- the second element is fixed to the chassis of the vehicle and the first element is secured to the seat fastening base.
- the kinetic energy of the occupant of the seat is gradually absorbed by allowing a slight movement of the seat forward or backward to limit the stress experienced by the body of the passenger.
- the vehicle advantageously comprises a slideway, said slide comprising a fixed section and a movable section able to slide relative to each other in the direction of deformation, in which the first element is constituted by the fixed profile of the slide.
- the vehicle comprises a slide, said slide comprising a fixed profile and a movable section in which the first element is welded to the fixed profile of the slide.
- FIG. 1 illustrates a seat comprising a first embodiment of a device for absorbing energy, in rotation, according to the invention
- FIG. 2 illustrates on an enlarged scale the reference detail II of the energy absorption device of FIG. 1, before impact,
- FIG. 3 illustrates, according to FIG. 2, the reference detail II, after shock,
- FIG. 4 is an exploded perspective view of a vehicle comprising a second embodiment of a translational energy absorbing device according to the invention
- FIG. 5 is a view in median section of the vehicle of FIG. 4;
- FIG. 6 is an exploded perspective view of a vehicle comprising a variant of the second embodiment of energy absorption device, in translation, according to the invention
- FIG. 7 is a view in median section of the vehicle of FIG. 6.
- FIG. 1 illustrates a seat 10 of a motor vehicle essentially comprising a seat structure 6, a backrest structure 8, a rotary articulation device 22 and an energy absorption device 1.
- the rotary articulation device 22 is interposed between the energy absorbing device, more specifically an adapter 2 and the backrest structure 8. It makes it possible to adjust the inclination of the backrest structure 8 with respect to the structure 6. Being well known in itself, in particular of the type of grain joint or continuous joint type, the device articulation in rotation 22 will not be detailed further.
- the energy absorbing device 1 comprises the adapter 2 held on the seat structure by means of a pivot 32 and a fixing screw 4 screwed into the seat structure 6. It absorbs the energy of the seat occupant 10 in the event of impact, by allowing a controlled rotation of the backrest structure 8 relative to the seat structure 6 by controlled deformation of the adapter 2.
- the adapter 2 is constituted by a shaped plate having a substantially constant thickness. It has a hole 12 and a succession of cuts 14a, 14b, 14c, in the example illustrated three cuts, succeeding one another in a direction of deformation X.
- the deformation direction X extends substantially circumferentially with respect to the pivot 32, with a slight deviation due to an overall deformation of the adapter 2.
- the cutouts 14a, 14b, 14c define between them bridges 16a, 16b, 16c, also three in number in the illustrated example.
- the bridges 16a, 16b, 16c have substantially an arcuate shape having a substantially constant radius of curvature R. They have a width l a , l b , l c according to the direction of deformation X which is substantially constant over their entire length .
- the bridge 16a located closest to the rod of the fixing screw 4 may, however, have a greater width in the center than at its ends.
- the cutouts 14a, 14b, 14c are delimited in the direction of deformation X by the bridges 16a, 16b, 16c and in a direction of elongation Y transverse to the deformation direction X each by two longitudinal edges respectively 18a, 19a; 18b, 19b; 18c, 19c.
- the longitudinal edges are substantially rectilinear and define two suites 18a, 18b, 18c; 19a, 19b, 19c of longitudinal edges corresponding to each of the short sides of the cuts.
- the longitudinal edges of each of its suites extend substantially parallel and in the extension of each other.
- the adapter 2 thus has a substantially ladder-shaped zone convergent amounts towards the hole whose bars are formed by the bridges and the amounts by the longitudinal edges.
- the cutouts 14a, 14b, 14c have between said longitudinal edges 18a, 19a; 18b, 19b; 18c, 19c a length respectively L a , L b , L c increasing as a function of 1 'distance from the cut with respect to the hole 12 and the rod of the fixing screw 4.
- the variation in length of a cutout the next is between 0.25 millimeters and 2 millimeters, preferably of the order of 1 millimeter.
- the lengths L a, L b, L c are respectively equal to 14, 15 and 16 mm and the hole 12 is 13 mm along the direction of elongation Y.
- the occupant of the seat 10 exerts a very high pressure on the backrest structure 8 of the seat, tending to pivot the adapter 2 about the pivot 32 and to bring the bridge 16a against the fixing screw rod 4.
- the pressure exerted by the fixing screw 4 by means of a washer compressing the adapter 2 between the seat structure 6 and the head of the fixing screw 4 generates a friction s Opposing the displacement to the rotation of the adapter 2 with respect to the fixing screw 4 and to the seat structure 6.
- the rod of the fixing screw exerts a force on the first bridge 16a tending to deform the bridge in the direction of deformation X and to stretch in the direction of elongation Y. If the force exerted on the first trigger guard 16a exceeds the mechanical strength of the material constituting the adapter 2, the bridge 16a breaks along uneven rupture edges 38a, 39a in the extension of the hole 12 and substantially continuing through the longitudinal edges 18a, 19a respectively.
- the longitudinal edges 18a, 19a are slightly set back (more apart from each other) with respect to the rupture edges 38a, 38b, so that the bridge 16a is not subjected to a very high friction against the longitudinal edges 18a, 19a, especially since the bridge 16a has a circular arc shape whose arrow is directed in the direction of movement of the bridge in the direction of deformation X.
- the rod of the fixing screw 4 exerts a force on the second bridge 16b, away from the hole 12.
- the bridge 16b deforms to rupture if the force is high enough, which generates edges at break 38b, 39b slightly farther apart than the break edges 38a, 39a since the longitudinal edges 18b, 19b are farther apart from each other than the longitudinal edges 18a, 19a.
- the bridge 16a can therefore pass between the rupture edges 38a, 39a without undergoing very high friction.
- the device has been described in connection with a high speed rear impact in which the bridges break and dissipate energy, it will be appreciated that the device is also advantageous for resiliently absorbing low speed impact energy.
- the fixing screw 4 of circular section illustrated in the embodiment of FIGS. 1 to 3 instead of the fixing screw 4 of circular section illustrated in the embodiment of FIGS. 1 to 3, provision could be made for an element of a different section, for example with a substantially flat face coming into contact with the bridges. .
- the contact with the jumpers must be relatively wide so as to promote breakage of the bridges along the longitudinal edges of the cuts.
- the rolling direction of the plate is preferably arranged parallel to the elongation direction Y.
- FIGS. 4 and 5 illustrate a portion of vehicle 110 equipped with an energy absorbing device 101 and essentially comprising a frame 124 and a slideway 126 fixed to the frame by means of a fixing screw 104 intended for supporting a seat and comprising in particular a fixed section 102 and a movable section 130.
- the movable section 130 is slidable relative to the fixed profile 102 in the direction of deformation X to adjust the seat position in this direction.
- a locking device (not shown) in position of the movable section 130 with a fixed profile ratio 102 makes it possible to maintain the relative position set when the vehicle is used. Such a locking device is well known per se, it will not be more detailed.
- the energy absorbing device 101 is partially integrated with the fixed profile 102, said fixed profile 102 being constituted by a metal plate of substantially constant thickness shaped and comprising a hole 112 and two successions of cuts 114a, 114b, 114c, 114g, 114h; 115a, 115b, 115c, 115g, 115h extending on either side of the hole 112 in a substantially symmetrical manner, in the illustrated example each of the successions comprises eight cuts succeeding one another in the direction of deformation X.

- the bridges 116a, 116b, 116c, 116g, 116h; 117a, 117b, 117c, 117g, 117h have substantially an arcuate shape having a substantially constant radius of curvature R. They have a width 1 in the direction of deformation X which is substantially constant over their entire length.
- the bridges 116a, 117a located closest to the rod of the fixing screw 104 for each of the successions may, however, have a greater width in the center than at their ends.
- the cutouts 114a, 114b, 114c, 114g, 114h; 115a, 115b, 115c, 115g, 115h are delimited in the direction of deformation X by the bridges 116a, 116b, 116c, 116g, 116h; 117a, 117b, 117c, 117g, 117h, and in a direction of elongation Y transverse to the deformation direction X each by two longitudinal edges respectively 118a, 119a; 118b, 119b; 118c, 119c; 118g, 119g; 118h, 119h; 120a, 121a; 120b, 121b; 120c, 121c; 120g, 121g; 12Oh, 121h.
- the longitudinal edges are substantially rectilinear and define, for each succession of cuts, two suites 118a, 118b, 118c, 118g, 118h; 119a, 119b, 119c, 119g, 119h; 120a, 120b, 120c, 120g, 12Oh; 121a, 121b, 121c, 121g, 121h of longitudinal edges corresponding to each of the short sides of the cuts.
- the longitudinal edges of each of its suites extend substantially parallel and in the extension of each other.
- the cutouts 114a, 114b, 114c, 114g, 114h; 115a, 115b, 115c, 115g, 115h have between said longitudinal edges 118a, 119a; 118b, 119b; 118c, 119c; 118g, 119g; 118h, 119h; 120a, 121a; 120b, 121b; 120c, 121c; 120g, 121g; 12Oh, 121h a length respectively L a , L h increasing as a function of the distance from the cutout relative to the hole 112 and the rod of the fixing screw 104.
- the variation in length from one cutout to the next is between 0.25 millimeters and 2 millimeters, preferably of the order of 1 millimeter.
- the rod of the fixing screw 104 exerts a force successively on the various bridges 116a, 116b, 116c, 116g, 116h arranged in before hole 112, successively deform the succession of bridges in the direction of deformation X and stretch in the direction of elongation Y until they break successively.
- Increasing the width of the cutouts 116a, 116b, 116c, 116g, 11bh and the arcuate shape of the jumpers 116a, 116b, 116c, 116g, 11bhh prevents said jumpers 116a, 116b, 116c, 116g, 11bh. submitted to a very high friction against the longitudinal edges 118a, 119a; 118b, 119b; 118c, 119c; 118g, 119g; 118h, 119h.
