Definitions

  • the invention relates to an attenuator and a seat for a land vehicle, which is equipped with at least one attenuator according to the invention.
  • a land vehicle which is equipped with at least one attenuator according to the invention.

  • the invention is based on the object to provide an attenuator, which has an improved shock absorption over conventional attenuators. It is also an object of the invention to provide a seat for a vehicle, with which the person is protected from external shock effects.
  • an attenuator which has two points of attack to initiate impulsive forces occurring in the attenuator. Furthermore, the attenuator has fasteners over which the attenuator can be attached. Preferably, the attachment points are arranged at the points of attack, so that the force can be applied to the attenuator by the fasteners.
  • the attenuator according to the invention further comprises an absorbent, which is able to absorb introduced forces and thereby dampen the impulsive force effects occurring.
  • an elastic material which returns after application of force back to its original position.
  • the elastic material according to the invention has a force limit up to which the fabric acts elastically. If this force limit is exceeded, the absorbent is deformed. The deformation also absorbs the applied force and converts it into deformation work.
  • the absorbent is integrated into the damping member or the material of the damping member itself is designed as an absorbent.
  • the attenuator is made of wall mount.
  • the attenuator is arranged between the element to be damped and a wall.
  • the fasteners a simple installation on the wall and the element to be damped is possible.
  • the attenuator is designed as a belt.
  • the belt acts by its physical properties as an absorbent.
  • the belt is provided for this purpose with an elasticity and / or running multi-layered.
  • the material of the belt itself is the absorbent.
  • the absorbent may also consist of seams which connect at least two layers of belts together. The possible deformation work of the absorbent acts here by the separation of the seams under force. Thus, the seams are the absorbent. These can be integrated at least partially into the belt.
  • the seams of the belt are preferably arranged parallel to each other and running transversely to the belt. This creates a number of mutually parallel seams which extend at a distance from each other transversely to the belt. The distances can be the same or different for all seams. These seams are provided at least partially on a belt.
  • An inventive belt can be articulated with its points of attack on a seat and / or on the chassis of a vehicle, in particular on the wall of the vehicle.
  • the belt may be arranged so that a person is protected on the seat or moving parts of the seat are damped.
  • the strap may be hinged to the seat and back of the seat to cushion a hinged seat. In an exemplary force action from below, the force then acts on the seat.
  • the inertia of the person on the seat can dampen an upward movement of the seat when an attenuator according to the invention is designed as a belt and is hinged to the seat and the seat back. Likewise, this is an articulation on the seat and chassis conceivable.
  • the damping members are configured to be deployed in a vehicle to dampen a vehicle seat against impact forces acting on the seat.
  • at least one inventive attenuator at the seat of the vehicle.
  • the seat can be damped by arranging at least one damping element between the seat and the vehicle wall.
  • the seat can also be equipped with appropriate straps. A combination of belt and Wandhait ceremonies is also possible.
  • the attenuator consists of an elastically deformable material, which is designed plate-shaped.
  • a plate-shaped attenuator element to be damped, for example, a seat at a suitable location, for example, arranged and fixed to a vehicle.
  • the material properties are chosen so that the plate-shaped attenuator does not deform under normal load of the seat and under normal load during operation of the vehicle. This also applies to fluctuations in temperature, humidity and comparable environmental parameters of the vehicle.
  • the plate-shaped damping member may have corresponding fastening elements, such as bores, angles or the like, so that the seat can be arranged and fastened to the vehicle via the damping member.
  • the damping member is integrated in a belt, for example, with which the person sitting on the seat can buckle. It is provided that in the region in which the belt forms the damping member, at least two layers of the belt material are arranged substantially congruent one above the other.
  • the abovementioned attenuators can of course also be used in combination with one another for a member to be dimmed, for example a seat. For this purpose, then the wall-mounted attenuator and / or the integrated in the belt Dämpfungsgiied can be used.
  • a plurality of seam lines are at intervals to each other attached to each other, which connect the two substantially nationwide mutually arranged layers of webbing together.
  • the belt is connected in the usual way, on the one hand with the seat and on the other hand with the chassis or again with the seat.
  • the belt can also be connected to a wall.
  • Fig. I An inventive seat with attenuators and back
  • an attenuator 1 is provided, which has two points of attack 2. On each side of the attenuator 1 fasteners 3 are arranged at the points 2. Between the points of attack is a Absorptionsmittei, which causes the damping of the damping song 1.
  • the absorbent may be designed as a material of the attenuator 1 for this purpose. However, it could also be arranged integrated in the attenuator 1.
  • the attenuator 1 and the absorbent have a force limit up to which the attenuator behaves elastically. When force is applied, the damping is achieved by the elastic behavior. If the acting force is above the force limit, a deformation of the attenuator 1 takes place. In this case, at least a part of the acting force is converted into deformation work on the attenuator.
  • a seat 10 is connected to a wall of a vehicle.
  • a deformation is realized in that the two longitudinal axes of the fasteners 3 are sheared and this shear up to a Force limit elastic acts and above the force limit causes the deformation of the attenuator 1.
  • the elasticity and the deformation is used to reduce the deformation energy and thus a significant attenuation of the impact force acting from the outside, so that the person sitting on the seat 10 is very well protected from this external influence.
  • the attenuator 1 is integrated in a belt 5, with which the person sitting on the seat 10 can buckle up. It is provided that in the region in which the belt 5 forms the attenuator 1, two layers of the belt material are arranged substantially congruently one above the other.
  • the belt 5 can be attached to the seat, to the wall of the vehicle, to the chassis of the vehicle or in combination of the aforementioned.
  • the belt 5 is connected in the usual way on the one hand to the seat 10 and on the other hand to the chassis 11 or again to the seat.
  • the fastenings of the straps 5 form the Befest Trentsseiemente 3 of the attenuator 1 and the ends of the belt 5 form the points of attack. 2
  • the several in the longitudinal course of the belt 5 in succession and arranged parallel to each other seam lines cause a kind of predetermined breaking point, since the seams tear in succession from the outside successively from the outside and thereby reduce the impact energy.
  • a seat 10 of a vehicle is shown, which is connected by means of the attenuator 1 via fasteners 3 or the like to the seat 10.
  • the attenuator 1 is also connected via fasteners or the like to a wall, not shown, of a vehicle.

  • the seams running parallel to one another and transversely to the belt 5 in this case connect two layers of the belt 5.
  • the belt 5 itself is multi-layered in the region of the seams. This can be carried out by loops, which forms the belt 5 in the region of the seams, but the belt 5 can also form the multilayer region by overlapping superimposing a plurality of belt pieces.
  • seams When force is applied to the belt at the points 2 then a shearing force acts on the seams, which can thereby be separated and cause the damping of the attenuator 1.
  • the seams can connect two layers as shown, but they can also be made continuous through all layers.
  • the different seams can be made of different materials, with different tear behavior.
