Definitions

  • the invention is directed to a child seat for transporting a child in a vehicle, preferably in an upright sitting position, with a seat surface and a backrest, furthermore with lateral supports in the region of the trunk of a child, and optionally with a headrest and / or side armrests.
  • Child car seats are exposed to significant peak forces in an accident, which must be kept away from the child as possible to minimize the injuries of the child in an accident.
  • forces acting in or against the direction of travel in a frontal impact of one's own or a subsequent car there are also laterally acting forces, which are triggered by cars bumping on one side of the vehicle.
  • Such a side impact can be far more critical for a child seat or seated child than a frontal impact, because the crumple zone of the body is significantly less against a side impact than in a frontal impact, where the engine or trunk can absorb significant forces due to severe deformation. before the actual passenger cell is affected at all.
  • the child seat which is usually made of plastic, will not succeed in doing so, which the body made of robust metal is unable to do: to avoid a collision of the child due to the penetrating parts. Then the child seat but at least the nature of this impact for the child as compatible as possible.
  • damping of a lateral impact means that the peak values of the acting forces or accelerations that occur over a few milliseconds are reduced and, instead, the duration of the force action is instead lengthened, for example.
  • a lateral impact means that the peak values of the acting forces or accelerations that occur over a few milliseconds are reduced and, instead, the duration of the force action is instead lengthened, for example.
  • a device has a limited internal elasticity, ie deformability. Similar to a cushion, it lays itself against any penetrating, hard parts and thereby relieves a collision of the child while it temporarily deforms. Of less importance is the absolute stability of a side support, which could not be large enough anyway to keep the penetrating part away from the child. Rather, more important is an inner deformability, for example, compressibility, which allows it to be compressed in a collision like a pillow. Another aspect is a spatial distribution of acting forces.
  • the invention can remedy this by distributing such selective acting forces over larger areas, so that local pressure peaks on the child's body are avoided.
  • the side supports should have sufficient stability so as not to be penetrated by smaller objects, but at most be pushed away.
  • the device according to the invention therefore places itself outside the actual side support in the event of a lateral impact and tries to keep it in shape as much as possible. If the side support is not damaged, in particular not penetrated, a first concern of the invention has already been achieved: Pointing force peaks are distributed over the entire surface of the side support and thereby avoid local pressure peaks or at least significantly mitigated. The intact remaining surface of the side support in turn supports the damping device and forces the same to close. deform, for example, to compress. During the compression, ie compression of the damping device, there is a relative movement between its inside and outside, wherein the inside significantly slower and / or less than their outer side moves. Although the child's impact starts earlier than without the cushioning device and lasts longer than without it, it is gentler on the child because not only local but also temporal peaks in pressure are worn away as much as possible and thereby defused.
  • the device for damping a lateral impact on a lateral support in the trunk area of the child has one or more stiffening ribs which run along the respective side support.
  • Such stiffening ribs extend at least partially approximately perpendicularly from the respective side support to the outside and therefore fulfill several functions: On the one hand get their peripheral, outwardly projecting areas early contact with a penetrating object and thus ensure an early onset of child side impact, so the Shift force peaks partially forward against the time axis. On the other hand, they absorb punctiform forces and distribute them at least along their foothold on which they are connected to the side support. The area distribution can then take place within the side supports themselves.
  • the invention recommends that one or more stiffening ribs have a flat shape, in particular similarly applied flags. These stiffening ribs derive their stability more from their extension perpendicular to the surface to be stiffened than from their extension parallel to this surface. Consequently, a corresponding, elongate cross-section with a predominant extent perpendicular to the stiffening surface, at least in the region of the foot point, where the relevant stiffening rib merges into the surface to be stiffened results.
  • the surfaces of one or more stiffening ribs can follow a curved course.
  • the elasticity of these stiffening ribs in general increases because their course aligns more and more towards their peripheral area parallel to the respective side support surface and thus in a side impact less in the lateral force direction transverse to the sitting or driving direction, but obliquely or even transverse to this direction of force, so that the stiffening rib does not have to deform in its plane, but approximately perpendicular to it.
  • the thickness of the stiffening ribs their number, width, material and in particular their curvature, therefore, the elasticity of a side support can be specifically influenced.
  • the invention can be further developed such that the surface of one or more stiffening ribs is curved in one direction only, not in a direction approximately perpendicular to it.
  • This measure not only creates extremely ordered conditions in that all stiffening ribs can be curved approximately in the same direction, but it also facilitates the production of a corresponding molding for one or both side supports, possibly integrally molded together with a backrest part, by using a (inner) mold in the longitudinal direction of the stiffening ribs, in which they are not curved, can be pulled out.
  • the surface of one or more stiffening ribs is curved only in an approximately vertical direction, not in the sitting or driving direction. Since the stiffening effect of the stiffening ribs in their longitudinal direction is usually stronger than transverse to it, can with a such a design rule can be achieved that the free leading edges of the side supports connected along their rear area with the backrest in a side impact of a deflection inward oppose the greatest possible resistance.
  • the curvature of a stiffening rib approximately follows a section of a cylinder jacket surface. It may be a general cylinder, so not necessarily with a circular base. However, the lateral surface should be smooth, that is buckling-free arched, because each kink would adversely affect the stability of the respective stiffening rib due to its extremely small radius of curvature.
  • the production of an injection-molded part offers the possibility of creating a stiffening rib which is free of mechanical stresses and yet gently curved and which, in a force-free state, endeavors to maintain its predetermined curvature.
  • the cylinder whose lateral surface follows the surface of a stiffening rib should have an elliptical or circular cross-section.
  • the lateral surfaces of such geometric body are curved at each point and thus give the arrangement a particularly high stability, as it is in a similar form, for example. Also found in pipes that are also prone to kinking.
  • the ratio from between the long semiaxis a and the short semiaxis b of the cross-sectional area of a cylinder whose lateral surface follows the surface of a stiffening rib is smaller than 2: 1, preferably smaller than 1.5: 1, then the radius of curvature changes over the entire area a stiffening rib only relatively little, and due to such homogeneous properties such a stiffening rib receives a maximum of stability.
  • the invention further provides that the long semiaxis a of the cross-sectional area of a cylinder whose lateral surface follows the surface of a stiffening rib, approximately in the vertical direction, the small semi-axis b, however, approximately horizontally and transversely to the sitting or driving direction.
  • the outer, flat arched and also to the respective side support approximately parallel areas of a stiffening rib are therefore more elastic than the adjoining areas near the side support.
  • the damping device initially yields strongly and then becomes increasingly rigid.
  • the stiffening ribs along their rectifyaklinien should impinge almost perpendicular to the outside of the respective side support, ie at an intermediate angle of more than 60 °, preferably more than 70 °, in particular more than 80 °.
  • These base points of the stiffening ribs oriented approximately perpendicular to the surface to be supported, with their comparatively high rigidity, ensure the high dimensional stability of the side supports as a whole.
  • the invention also provides - follow the actual side support between two whoticianlinien adjacent stiffening ribs a curved course, so that again results in an arrangement similar to a (barrel) vault.
  • the cusp line should be laterally outboard of the side support, ie, the side support bulges inward toward the seat center between two adjacent stiffening ribs.
  • the side support is capable of doing so is to support a child's body as it accelerates without losing its shape. The side support is thus able to reliably perform its function of protecting the child even under the extreme conditions of a direct side impact against the child seat.
  • a particularly advantageous arrangement results from the fact that at least one pair of stiffening ribs, which are each connected at a NASAtownlini with the outside of the respective side support, to (each) a single stiffening rib with two who Vietnameselinien and between these satisfied Vietnameselinien everywhere kink-free course are formed together.
  • Such a two-toe-line arrangement with a continuous camber therebetween corresponds to a complete barrel vault, thus providing extremely high stability both against the primary impact direction in a side impact and in terms of uniform, symmetrical dissipation of that impact force without lateral displacement of the child seat ,
  • a further optimization undergoes the arrangement according to the invention in that at least two stiffening ribs along a common edge are connected to each other. This possibility is created by the curved, in particular cylinder jacket-shaped arched course of the stiffening ribs. Because a cylinder jacket-shaped stiffening rib would therefore return to the Stanfordsteifenden side support after half a circuit, if they did not previously on the adjacent stiffening rib. The latter occurs, however, when the distance between two adjacent stiffening ribs is smaller as the parallel to the semiconductor laser diameter of the buckling cylinder.
  • the distance between thetician Vietnamese Vietnamese ribs is equal to or less than the 1, 6 times the mean radius of curvature of a stiffening rib, in particular equal to or less than 1, 2 times the mean radius of curvature of a stiffening rib.

  • the invention allows a development to the effect that a connecting edge between two stiffening ribs follows an approximately straight stretched course. Such a course is self-evident when the

  • a middle stiffening rib undergoes a connection with each of the two adjacent stiffening ribs, the relevant However, joint edges preferably do not coincide. Rather, a stiffening rib is connected at different distances from its furnish Vietnameseline with one of the two adjacent stiffening ribs.
