Device for influencing a rearward displacement of a seat and seat
The invention relates to a device for influencing a
Shift back of a seat.
The apparatus further relates to a seat, especially vehicle seat comprising such a device.
In traffic accidents, particularly in rear-end collisions of motor vehicles, it may be due to a rear occurring forces
Downward movement, that is movement towards a vehicle rear and -bodens, a vehicle seat in particular of a seat back or a backrest part, based on a mounting position of the vehicle seat used in a vehicle. In this way, there is a danger that the vehicle seat is at least partly deformed in an undesirably large extent, whereby uncontrolled movements of the vehicle seat and resulting hazards sitting on the vehicle seat and other persons located in the vehicle results.
From the prior art various devices are known that positively influence a shift back of the vehicle seat, are for example, by selectively additionally triggered in selected areas kinematic movements exclusively in the event of a crash and executed. Some known devices are based on different, each complex mechanisms with a plurality of moving parts, typically a movement of these components is triggered due to mechanical or electronic signals. other known
Solutions based on occurring exclusively in the event of a crash deformations of connection parts between, say, the
Backrest part and the seat substructure, which solutions, however, be comparatively large,
cause unfavorable shift back corners of the backrest parts in a crash.
The invention has the object of providing an over the prior art improved apparatus for influencing a rearward displacement of a seat and an improved seat, especially vehicle seat specify.
With regard to the device, the object is achieved by the features indicated in claim 1. and with respect to the seat by the features specified in claim 10. Advantageous embodiments of the invention are subject of
The inventive device for influencing a rearward displacement of a seat, in particular a backrest part, comprises at least called a in a joint region of the squab of the seat, and the seat substructure is arranged a deformation element, wherein the deformation element is formed such that it at one on the seat part and / or the backrest part applied force below a predefined torque curve
is deformable, the definition of which may be dependent on requirements of the respective vehicle crash.
The device allows in a simple and reliable way
Influencing and controlling the rearward displacement of the seat, in particular the backrest of the seat. The seat is as a vehicle seat. Thus, it is possible that the by deformation
Deformation element acting with a predefined torque curve during an accident or crash on the vehicle seat force to absorb partially or completely, and thus to realize a desired return or displacement of the vehicle seat by appropriate dimensioning and design of the deformation element to control. In this way, particularly high, acting on the person forces are avoided, especially during a crash.
The arrangement of the deformation element in the immediate vicinity of a pivot point of the seat substructure enables a relatively simple construction, since the movement as such, namely the pure
Rotational movement, can be specified from the hinge point, and thus, the deformation element is in principle easy Artwork as arranged parallel to the hinge component. Furthermore, it is avoided that the vehicle seat is deformed in an unfavorable large extent, thereby caused thereby, uncontrolled movements of the vehicle seat and resulting hazards on the
Car seat sitting and other persons located in the vehicle can be avoided or at least reduced.
Further, the deformation element allows at least one additional support in the vehicle transverse direction as Y-direction hereinafter, during an accident or crash If no additional supporting element. By means of the deformation element thus a kinetic energy absorbing member is realized that as a standardized
Setting component can be integrated as a modular unit in a seat structure and thus use of vehicle-specific structural parts, such as lower fitting parts or seat frame side members, at least partly replaced, and at least reduces their number of variants. Furthermore, the Deformationselennent a very small space requirement and can be integrated in simple manner into an existing seat constructions. Due to the basic design concept in terms of an amount of energy absorption and thereby a shared path by simply varying component parameters by the solution to different requirements in a particularly simple way is customizable.
In a possible development of the device, the seat part has two side parts and wings, wherein a connecting these transverse strut is arranged between the wings, whereby a deformation element is arranged in the joint region at least on one side between one of the side portions proximate swing arm and one end of the transverse strut. This allows a height adjustment of the vehicle seat is relieved in the accident or crash. Further, it is possible in a simple manner that by arranging the at least one deformation element between the side section and cross-member, the deformation of the backrest part and the seat part on both sides, ie in particular on a side facing a vehicle door side and a vehicle door opposite side is symmetrical. One possible embodiment of the device provides that the
Deformation element is formed of at least two parts. The parts can be homogeneously having from one material or from several, for example, different properties may be formed materials. A material elongation, hardness and / or strength as well as a structure of each part are defined according to the torque request and adapted to the turning angle. The separate parts are by means of conventional connections, for example, material-fit, form-fit or non-positive connection, for example by weld, rivet joint, adhesive joint, fixed to each other. Another possible embodiment of the device provides that one of the parts is harder than the other part. In other words, the
is a deformation element of at least one soft and at least formed of a hard portion, the soft and the hard member are joined together or separately formed. By a dimensioning of the two parts and selecting the hardness of the two parts of the deformability of the deformation part and, consequently, the predefined
Torque curve can be predetermined in a simple manner. According to a further development of the apparatus, a part of which forms a base and the other part is a support part, wherein the support member is so connected to the base part, that the support member relatively towards the base part
is deformable or elastically adjustable. For example, the base part and the supporting part via at least one or more elastically deformable absorbing parts, such as ribs, connected to each other, by
corresponding dimensioning and configuration of the absorbent parts in a simple manner, the torque curve in rearward displacement of the seat is pre-definable. Alternatively or additionally, the deformation element may comprise recesses, by appropriate dimensioning of the recesses, the torque curve in rearward displacement of the seat is pre-definable also in a simple manner. One possible embodiment of the device provides that at a
is carried out exceeds a predetermined limit value of the force acting on the seat part and / or the backrest part a force generating an operative connection between the at least two parts. For example, is reached during an accident and the soft part in operative connection with the hard part that the predefined torque curve is possible by appropriate design and dimensioning of the two parts.
For example, the at least two parts for easy and
reliable generation of these active compound in a contact region in each case a profile, for example a tooth profile or cornice on.
A further development of the device provides that at least one of the parts is formed as a ring. Thus, in a simple and reliable manner can be ensured that the return displacement of the seat, in particular of the backrest part of the seat, by rotation and / or deformation to the ring or the ring is produced around the other part. Hereby may be achieved that a relative movement of the backrest part to the seat part at a predetermined position, ie in the hinge region at the position of the deformation element, is carried out.
In an alternative embodiment, the deformation element may be formed of a part whose material has a corresponding different elongation behavior and / or corresponding different strengths. Such a deformation element, for example, as a
Double ring formed by two rings bonded webs. In this case, the webs deform during a crash between the two rings, so that one of the rings rotates by a certain angle relative to the other ring. This results in a pre-defined
Torque and affect the rearward displacement of the seat, in particular of the backrest part, depending on the dimensioning of the webs to the desired extent.
The seat according to the invention, in particular vehicle seat, comprising a seat part, a back part and a device according to the invention or
Features and refinements of this. The device allows, due to the deformation of the deformation element below a predefined torque curve during an accident or in the event of a crash in a force acting on the seat part and / or the backrest part force influencing or controlling the rearward displacement of the seat,
in particular of the backrest part, and thus an increase in a

In this case, one of the parts is formed 4.1 of a hard material and the other part of a softer material 4.2. In the embodiment the parts 4.1, 4.2 are formed separately. The hard part 4.1 is located at one end of the transverse strut 6 and fastened. The other, especially the soft part 4.2 is fastened to the respective side part 5 of the seat part 1 .2.
Alternatively, the deformation element 4 may be integrally formed as
Two-component element, in particular an injection molded part, be made of two different materials. Alternatively, the soft and hard parts 4.1 may be 4.2 interconnected.
The deformation element 4 is formed so that 4.2 in such an accident occurs during the soft part in operative connection with the hard portion 4.1 and reached the conclusion that a predefined torque curve by an appropriate design and dimensioning of the two parts 4.1, 4.2 is also possible.
To this end, the two parts 4.2 4.1, the edge in the contact area

Figures 5 and 6 show schematically in perspective view an enlarged view of the hinge portion 7 of the lower seat part 1 .2 with an alternative embodiment of a deformation element 4. The deformation element 4 is integrally formed. For example, the integral deformation element 4, two radially spaced-apart sections 4.3, 4.4, hereinafter also referred to as rings 4.3, 4.4 at. The rings 4.3, 4.4 are connected by further portions 4.5, hereinafter also referred to as webs 4.5, connected to each other. 4.5 The webs are inclined between the two rings 4.3, 4.4. The inner ring 4.4 is fixed to the cross member. 6 The outer ring 4.3 is fixed to the side member. 5 In an accident, the inner and outer rings 4.3, arranged on the side part 5 or on the transverse strut 6 stably and firmly 4.4 remain. By a shift back in the direction of rotation R as a result of the accident, the outer ring is rotated 4.3 and as a result, the webs deform 4.5. By appropriate design of the webs of the rings 4.5 and 4.3, 4.4 a defined torque curve in the return shift in the rotational direction R of the backrest part 1 .1 be predetermined and adjustable. By a corresponding inclination of the webs 4.5, a desired rotation and a deformation can be obtained and set.

It is an axial external annular surface F1 of the wide ring 4.6 which abuts the side member 5, attached thereto. The opposite and axially inner annular surface F2 of the wide ring 4.6, which bears against the cross-member 6 is connected thereto. 4.7 the recesses are so placed in the ring 4.6, that inclined webs are formed 4.9. In an accident, the axial annular surfaces remain F1, F2 stably and firmly so that the ribs deform 4.9 and the outer annular surface F1 in a direction of rotation R
has the desired rotation and hence a defined
achieved torque curve.
In an accident, the annular surfaces remain F1, F2 stably and firmly at the
Side panel 5 and fastened to the transverse strut. 6 The outer annular surface F1 rotates in the direction of rotation R as a result of the backrest rearward displacement, thereby deform the webs 4.9 with a deformation angle D, so that one of two annular surfaces F1, F2, in particular the outer ring surface F1 has a desired rotation and hence a defined
achieved torque curve. In this case, the two annular surfaces F1, F2 may be formed of hard material and the webs 4.9 out of a softer material. Depending on the requirements for the torque curve of the annular surfaces can F1, F2 also

Figure 16A to 16C schematically show the deformation element 4 according to figure 15 in different views. The Defornnationselennent 4 is integrally formed. For example, the one-piece Defornnationselennent 4 is cup-shaped, wherein in a pot bottom, a circular segment is cut out, so that the
Deformation element 4 is annular. In particular, the deformation element 4 is a cup-shaped, reshaped sheet metal component which is at least partially designed as a circular segment.
For example, the deformation element 4 made of a steel, a so-called HSD steel (HSD = High Strength and Ducity), a so-called TWIP steel (TWIP = Twinning Induced Plasticity) or so-called TRIP steel (TRIP = transformation induced plasticity) educated.
In this case, the deformation element 4 comprises two spaced-apart rings 4.3, 4.4. A first ring 4.3 is arranged angled according to the pot to form a second ring 4.4, wherein the
Deformation element 4 has a substantially J-shaped or L-shaped cross section.
The rings 4.3, 4.4 are interconnected by means of webs 4.5. The webs extend between the two rings 4.5 4.3, 4.4 in the way that they have a nearly-parabolic transition to at least one of the rings 4.3, 4.4. This produces a particularly good

The in cross-section a long leg of the "J" or "L" forming ring 4.4 is fixed to the swing arm 5.1 of the side part. 5 One short
Legs forming ring 4.3 is fixed to the cross member. 6 In an accident, the rings remain 4.3, arranged on the side part 5 or on the transverse strut 6 stably and firmly 4.4. By a shift back in the direction of rotation R as a result of the accident, the ring twisted 4.3 and as a result, the webs deform 4.5. By appropriate design of the webs of the rings 4.5 and 4.3, 4.4 a defined torque curve in the return shift in the rotational direction R of the backrest part 1 .1 be predetermined and adjustable. By a corresponding inclination of the webs 4.5 or adjustment of the
parabolic waveform can have a desired rotation and a
be achieved deformation and set.
