Description

[0001] The present invention relates to a vehicle seat comprising a seat frame and at least one component of a comfort or safety system.

[0002] Vehicle seats no longer serve solely their original function of providing a seat for vehicle occupants. In modern vehicles, seats are often integrated into comfort systems, with components of these systems being incorporated into or even within the seats themselves. Further components that can be part of, or integrated into, a vehicle seat are conceivable in connection with vehicle safety systems, particularly seat belt systems. Therefore, there is a need to attach separate vehicle seat components as reliably and securely as possible.

[0003] For example, in connection with seat belt systems, it is known to attach corresponding components to the vehicle seat by means of connecting elements, whereby in the event of a crash, the released kinetic energy is dissipated due to plastic deformation of the connecting elements. Such a concept, in which a seat belt suspension is connected to a seat backrest by means of a crash element comprising several deformation elements, is known from DE 10 2011 012 461 A1.

[0004] Another concept for attaching a webbing guide to a seat is known from DE 10 2016 101 102 A1. This webbing guide comprises a pivot pin arranged to slide within a guide track. An elastic element within the guide track interacts with the pivot pin in such a way that the webbing guide is moved into a central position within the guide track.

[0005] From DE 198 02 028 C1, a backrest for a motor vehicle with a height-adjustable headrest is known. The headrest is connected to a cross member of the backrest via two guide rods that run through guide bushings. A cross piece connecting the guide rods on their underside is connected to the upper end of a tension spring, the lower end of which is connected to a lower cross member of the backrest. A coupling is also provided, by means of which the connection of the headrest to an adjustment motor can be released, whereby in this case the headrest is pulled downwards by the spring to the vicinity of the upper cross member of the backrest.

[0006] KR 10 2005 0 045 050 A discloses a vehicle seat with a headrest and a seat frame, wherein a pivoting bracket, articulated to the seat frame via a pivot joint and tensioned by a spring, is connected to the headrest. The headrest is attached to the seat frame via a rod that is received in a guide sleeve. In a home position of the headrest, a locking lug of a stop element is engaged in a first recess of the guide sleeve, so that movement of the headrest with respect to the longitudinal direction of the rod or guide sleeve is locked. In the event of an accident-related movement of the bracket and thus of the headrest together with the guide sleeve, the locking mechanism formed by the locking lug between the rod and the guide sleeve is released by the locking lug being pushed out of the first recess by means of a projection of the outer sleeve.A spring located below the rod in the guide sleeve then relaxes, so that the guide rod and thus the headrest is moved further upwards away from the seat frame until the locking lug engages in a second locking opening located above the first locking opening.

[0007] Another concept relating to a vehicle seat which has a safety belt guide arrangement is known from DE 10 2016 120 352 A1.

[0008] The present invention aims to provide an improved concept for attaching a component of a comfort or safety system to the vehicle seat, in particular with regard to the highest possible mechanical stability and the most advantageous behavior in the event of a crash.

[0009] According to the invention, the problem in a vehicle seat of the type mentioned at the outset is solved by attaching the component to the seat frame by means of at least one fastening means and by mounting it movably relative to the seat frame, wherein the fastening means comprises at least one elastic clamping element, by means of whose clamping force the component is pre-tensioned into a basic position, from which the component can be moved towards the seat frame by means of a force opposing the clamping force, wherein a movement of the component away from the seat frame is limited by the basic position.

[0010] The component of the comfort or safety system can be of a different nature. Ultimately, the concept according to the invention is applicable to any component that represents a separate part in relation to the rest of the vehicle seat structure.

[0011] The component can, in particular, be a ventilation device, such as a ventilation device according to the German patent application DE 10 2020 109 053 A1, filed on the date of the application. Reference is therefore expressly made to the disclosure content of this patent application. The component can also be part of a seat belt system and / or a loudspeaker and / or an ashtray and / or a control element for generating user-generated operating signals. The control element can be configured to generate operating signals that can be used during the operation of a vehicle in which the vehicle seat according to the invention is installed.

[0012] The elastic clamping element ensures that the component remains in its home position without any further force being applied, or automatically assumes this position. The component can be moved from its home position by applying a force, provided that the opposing force component of this force is greater than the clamping force itself. In this process, energy is stored in the elastic clamping element, increasing the clamping force, particularly according to Hooke's Law. When the opposing force decreases sufficiently or disappears completely, the elastic clamping element springs back, and the component returns to its home position.

[0013] The elastic tensioning element ensures that the component is held in its home position unless a further force is applied, or the applied force is insufficient. The preload of the component by the elastic tensioning element is preferably sufficient to prevent it from being exceeded during normal use of the vehicle seat, thus ensuring the component remains in its home position. The greater the preload of the elastic spring element, the greater the force required to move the component from its home position, and consequently, the more stable the component is held in that position.

[0014] On the other hand, the fastening device allows the component to spring back or compress against the force opposing the clamping force. This ensures that if a sufficiently large force acts on the component against the clamping force, it does not remain rigidly in its initial position but yields. This has a positive physical effect on a vehicle occupant who, for example, comes into contact with this component in an accident. For instance, the component may be positioned in the vehicle seat in the area of ​​the upper back or neck of the vehicle occupant. If another vehicle collides with the rear of the vehicle in an accident, the vehicle occupant is abruptly forced into the seat. According to the invention, the component is springable backward or away, thus preventing injury to the vehicle occupant.

[0015] Regarding the direction of the clamping force of the elastic clamping element, this force preferably points, in particular perpendicularly, away from the seat frame or a surface of the seat frame, so that the component moves from its initial position towards the seat frame, provided that the force opposing the clamping force exceeds it, whereby movement of the component away from the seat frame is limited by the initial position. In this embodiment, the elastic clamping element not only prevents the risk of injury to the vehicle occupant should they collide with the component, but the fastening device can also protect the occupant from a violent impact on the seat frame, since the elastic clamping element can absorb energy accordingly.

[0016] The vehicle seat can be multi-part. Preferably, the vehicle seat has a horizontal seat surface and a backrest that can be pivoted relative to the seat surface. Furthermore, the vehicle seat can have a headrest attached to the backrest. A central section of the backrest can be flanked on the left and right sides by a side bolster. The seat frame typically forms the supporting structure of the vehicle seat or the respective component of the vehicle seat. Preferably, the seat frame is a metallic frame composed of tubular and beam-like parts. The seat frame can comprise a U-shaped metal tube that can form corresponding longitudinal and transverse beams. The vehicle seat can be installed in a corresponding vehicle via the seat frame.

[0017] The vehicle seat can, particularly in the area of ​​the seat bolsters, have at least one side airbag that deploys in the event of a crash. The concept according to the invention is also advantageous with regard to this potential airbag, since the movable mounting of the component ensures that the deployment of the airbag is not obstructed by the component. Thus, the force opposing the tension force, which causes the component to rebound, can be generated by the deploying airbag, thereby ultimately clearing the airbag's deployment path.

[0018] In a preferred embodiment of the motor vehicle according to the invention, the component is guided in a linear manner by means of the fastening means. In other words, it can be provided that the component is guided in a linear motion path or direction by means of the fastening means, so that the component has one degree of freedom. Alternatively, but less preferably, it can also be provided that the motion path along which the component is guided has a curved shape. The motion path preferably leads towards the seat frame or is arranged at an angle, in particular at right angles, to a longitudinal axis of the approximately beam- or tube-like seat frame, so that the component can spring inwards or outwards in the direction of the seat frame.If the component is guided in a straight line, it is preferably provided that the direction of movement of the component and the clamping force that can be generated by means of the elastic clamping element extend along a common direction.

[0019] The fastening device can comprise at least one component-side and at least one frame-side support section, wherein the component-side support section bears against the frame-side support section when the component is in its home position. The clamping force exerted by the elastic clamping element thus results in the support sections being pressed against each other when the component is in its home position, forming a positive lock such that further movement of the component in the direction of the clamping force is not possible, or is blocked. The positive lock between the support sections ensures, in particular, that the elastic clamping element cannot relax, or, in other words, is clamped in such a way that the clamping force causing the component's preload is maintained when the component is in its home position.

[0020] As an advantageous further development of this embodiment, the fastening means can be provided to comprise a component-side and a frame-side cylindrical section, wherein one of the cylindrical sections is inserted concentrically into the other cylindrical section, so that the component is movably guided along the common longitudinal axis of the cylindrical sections, wherein the component-side or frame-side support section is an outwardly projecting projection of the inner cylindrical section and the other support section is an inwardly projecting projection of the outer cylindrical section. The two cylindrical sections are thus guided almost telescopically along their longitudinal axis, resulting in a straight path of movement for the component.The relative movement of these two cylinder sections with respect to their separation is limited by the fact that the projections of the cylinder sections abut each other, or rather, one projection runs against the other projection, with the component assuming its home position in this final position. The outer cylinder section is necessarily hollow to accommodate the inner cylinder section, which may optionally also be hollow. The component-side cylinder section is preferably a section projecting from the component, particularly perpendicularly. The same applies to the frame-side cylinder section, which may accordingly project from the seat frame.

[0021] To mount the component or fastener, the inner cylinder section can be inserted into the outer cylinder section against the force of the elastic clamping element, causing the cylinder sections and their projections to deform elastically in the radial direction. This continues until the projections, particularly those interlocking behind each other, engage and the component assumes its initial position.

[0022] The component-side or frame-side support section can be an outwardly projecting, particularly obliquely projecting, collar or barb of the inner cylinder section, and the other support section can be an inwardly projecting, particularly obliquely projecting, collar or barb of the outer cylinder section. Each cylinder section can have a collar or barb at its end facing away from the component or the seat frame, wherein the collars or barbs of the cylinder sections abut or engage with each other and are pressed against each other by the clamping force when the component is in its basic position. The collar can be continuous or interrupted. In particular, several barbs can be provided, preferably arranged equidistantly along the circumference of the respective cylinder section.It is possible for both cylinder sections to each have a collar or at least one barb. Likewise, it is conceivable that one of the cylinder sections has a collar and the other cylinder section has at least one barb, with the barb and the collar interlocking when the component is in its home position.

[0023] The elastic clamping element is preferably arranged along the common longitudinal axis of the cylinder sections, and is pre-tensioned under compression when the component is in its home position. In this embodiment, the inner cylinder section is also preferably hollow, with the elastic clamping element arranged along its longitudinal axis, which coincides with the longitudinal axis of the outer cylinder section. The elastic clamping element is supported on one side by the component, in particular a housing of the component, and on the other side by the seat frame or at least by a component associated with the component or the seat frame. Moving the component out of its home position is thus achieved by telescopically sliding the cylinder sections into one another, further compressing the elastic clamping element, and thereby increasing the clamping force.

[0024] Regarding the frame-side support section, it is preferably provided that it is attached to the seat frame, particularly to a bracket or side member of the seat frame, by means of a fastening strap, which in particular has a mounting base supporting the frame-side support section. A section of the fastening strap, which is preferably made of metal and can also be referred to as a fastening belt, surrounds the tube, bracket, or side member of the seat frame and is subjected to tensile stress such that a secure attachment between the fastening strap and the seat frame, and thus between the component and the seat frame, is achieved. Preferably, the mounting base is integrally formed or attached to the section of the fastening strap, with the frame-side support section, for example, the respective cylinder section, in turn being attached to the mounting base.The fastening strap can be attached to the seat frame according to the principle of a cable tie.

[0025] Regarding the specific arrangement of the component in the vehicle seat, it can be provided that it is embedded in a padding material, in particular a foam material, and / or arranged under a surface or an opening of a seat cover, in particular a leather one. Thus, the interior of the vehicle seat is bounded externally by the seat cover and preferably filled with the padding material. In addition to the component, the seat frame can also be embedded in the padding material. The padding material is typically easily deformable, so that the springback of the component in the vehicle seat according to the invention is not significantly hindered by the padding material.

[0026] If the component is a ventilation device, in particular according to the aforementioned German patent application DE 10 2020 109 053 A1, it may be provided that the component is a unit with a housing, in particular embedded in the upholstery material, wherein, for example, a fan for drawing in or blowing air into a passenger compartment of the vehicle, a heating device, a temperature control device, and a filter device for treating this air are arranged in the housing. The housing expediently has an air opening that leads into the opening of the seat cover.

[0027] The invention further relates to a vehicle, in particular a motor vehicle, comprising at least one vehicle seat according to the preceding description. All features, aspects and advantages explained in connection with the vehicle seat according to the invention are equally applicable to the vehicle according to the invention and vice versa.

[0028] The vehicle seat can be a driver's seat, a passenger seat, and / or a rear bench seat. Preferably, the vehicle seat or seat frame is attached to the vehicle body, for example, by means of a suitable mounting frame. Particularly preferably, the vehicle seat is movable along the longitudinal direction of the vehicle.

[0029] Further aspects, advantages, and details of the invention will become apparent from the exemplary embodiments presented below and from the figures. These show schematically: Fig. 1 an embodiment of a vehicle according to the invention, Fig. 2 an embodiment of a vehicle seat according to the invention of the vehicle made of Fig. 1, Fig. 3 a representation of the internal structure of the vehicle seat Fig. 2, Fig. 4 a detailed view of the vehicle seat fastening device Fig. 3, and Fig. 5 a detailed view of the components of the fastener Fig. 4.

[0030] Fig. Figure 1 shows a vehicle 1 according to the invention, in this case a motor vehicle. The vehicle 1 comprises several vehicle seats 2 in its passenger compartment 3, namely a driver's seat 4, a passenger seat 4, and a passenger seat 4. Fig. 1 passenger seat not shown, and a rear bench seat 5 arranged behind the driver's seat 4 and the passenger seat.

[0031] Details regarding driver's seat 4 will be provided based on the Fig. 2 explains, whereby the aspects set out below apply equally to the front passenger seat and the rear bench seat 5. The driver's seat 4, which is adjustable forwards and backwards with respect to the longitudinal direction of the vehicle 1, comprises a seat cushion 6, a backrest 7, and a headrest 8. The backrest 7 is pivotable about a horizontal axis relative to the seat cushion 6. The backrest 7 comprises a central section 9 and a side bolster 10 on each side of the central section 9. A side airbag 11 is also provided in the area of ​​the backrest 7, specifically within each side bolster 10.

[0032] Fig. Figure 3 shows the interior of the vehicle seat 2. The vehicle seat 2 consists of a frame-like seat frame 12, which is surrounded by a padding material 13 designed as foam. The seat frame 12 primarily provides the mechanical stability of the vehicle seat 2 and includes, for example, a U-shaped bent metal tube, which ultimately forms, among other things, a top crossbar and two longitudinal rails of the vehicle seat 2. The surface of the vehicle seat 2 is covered by a material in the Fig. 3 dashed lines indicating a leather seat cover 14 formed.

[0033] In the area of ​​the seat bolster 10, a component 15 is embedded in the upholstery material 13. The component 15 is, for example, a ventilation device which, according to German patent application DE 10 2020 109 053 A1, comprises a housing 17 containing a fan for drawing air into the housing 17 and / or blowing air into the passenger compartment 3, a heating device, a temperature control device, and a filter device for treating this air. The housing 17 has an air outlet opening that leads into an opening 18 in the seat cover 14. The component 15 is provided in two locations, namely on the left and right sides of the vehicle seat 2 in each of the two seat bolsters 10. The component 15 can also be part of a seat belt system, a loudspeaker, an ashtray, or a control element of the vehicle 1.

[0034] As from Fig. As can be seen in Figure 3, component 15 is attached to the seat frame 12 by means of a fastener 19. Details relating to the fastener 19 are shown in the following. Fig. 4 explains, which is an enlarged section of the in the Fig. Figure 3 shows the area marked by a circle. Component 15 is mounted so as to be movable in a straight line relative to the seat frame 12 by means of the fastening means 19, so that component 15 can move along a direction of movement 20 or along a movement path extending along the direction of movement 20, with details of this mobility being explained below.

[0035] The fastening device 19 comprises an elastic clamping element 21, namely, for example, a metallic coil spring. Alternatively, the elastic clamping element 21 can be made of plastic or an elastomer. The elastic clamping element 21 exerts a clamping force by means of which the component 15 is held in a position in the Fig. The basic position shown in section 4 is pre-tensioned. Details regarding this, in particular in connection with the detailed mode of operation of the components of the fastener 19, are explained below using the following. Fig. 4 and Fig. 5 explained, where Fig. 5 an enlarged section of the in the Fig. 4 shows the area marked by an oval.

[0036] The fastening element 19 comprises a component-side cylindrical section 22 and a frame-side cylindrical section 23. The component-side cylindrical section 22 is integrally formed on the housing 17 of the component 15. The frame-side cylindrical section 23 is attached to the seat frame 12 by means of a fastening band 24, which will be discussed in more detail later. The cylindrical sections 22 and 23 are hollow.

[0037] The frame-side cylinder section 23 is concentrically inserted into the component-side cylinder section 22, so that the frame-side cylinder section 23 can be referred to as the inner cylinder section and the component-side cylinder section 22 as the outer cylinder section. The cylinder sections 22 and 23 are telescopically movable relative to each other along their common longitudinal axis, which extends along the direction of movement 20. The elastic clamping element 21 is arranged along the common longitudinal axis of the cylinder sections 22 and 23, i.e., along the direction of movement 20. Consequently, the clamping force generated by the elastic clamping element 21 is collinear with the direction of movement 20.

[0038] The fastening device 19 further comprises a component-side support section 25 and a frame-side support section 26, details of these support sections 25, 26 being given by reference to the Fig. 5 will become clear. The component-side support section 25 is an inwardly projecting projection, namely an obliquely inwardly projecting collar 27 of the outer or component-side cylinder section 22. As a counterpart to this, the frame-side support section 26 is provided as an outwardly projecting projection of the inner or frame-side cylinder section 23, specifically as an obliquely outwardly projecting collar 28.

[0039] For the initial assembly of the fastener, the cylinder sections 22, 23 are pushed into one another against the force of the elastic clamping element 21, so that the inclined surfaces of the two collars 27, 28 slide along each other and the cylinder sections 22, 23 deform elastically in the radial direction until the collars 27, 28 snap into each other in an interlocking manner and the fastener 15 engages the Fig. 4 and Fig. 5 occupies the position shown.

[0040] The two collars 27, 28 are shown as complete circumferential features, but they can also be interrupted. Alternatively, the inwardly or outwardly projecting protrusion can instead be at least one barb. For example, several barbs can be provided, arranged equidistantly along the circumference of the respective cylinder section 22, 23. A combination of collars and barbs is also possible.

[0041] When component 15 is in its initial position, it is pre-tensioned by the clamping force of the elastic clamping element 21, which is subjected to compression. The elastic clamping element 21 is supported on one side by the housing 17 of component 15 and on the other side by the seat frame 12, with the support sections 25, 26, i.e., the collars 27, 28, bearing against each other due to the clamping force of the elastic clamping element 21. Specifically, the collars 27, 28 form a positive fit, so that, with respect to the Fig. 4 and Fig. 5, the component-side cylinder section 22 together with component 15 can only move along the direction of movement 20 onto the seat frame 12. Movement away from the seat frame 12 is not possible due to the positive locking between the collars 27, 28. Specifically, with regard to the Fig. 4 and Fig. Ultimately, only a movement of component 15 to the lower right is possible.

[0042] This configuration now results in several advantageous aspects regarding the fastening and / or mobility of component 15, which are explained below. Fig. 4 will be explained. As just explained, the only possible direction of movement of component 15, starting from the basic position, is direction 20 towards the seat frame 12. Movements of component 15 in any other direction are not possible due to the positive locking between the cylinder sections 22, 23 and the support sections 25, 26. Furthermore, movement along direction 20 towards the seat frame 12, i.e., in the Fig. 4 and Fig. 5 to the lower right is only possible if a force acting on component 15 exceeds the clamping force of the elastic clamping element 21. With regard to the Fig. This means that if a force acts on component 15 from the upper left, it will only move to the lower right if the force component opposing the tension force of the elastic clamping element 21 is greater than the tension force. In this case, the elastic clamping element 21 compresses, and consequently, component 15 retracts.

[0043] The Hooke's constant of the elastic tensioning element 21 is chosen such that the tension force is large enough that the component 15 only compresses under forces typically encountered during an accident. Thus, the component 15 does not rebound during everyday driving, as this would be undesirable for practical reasons anyway. In contrast, the compression of the component 15 during an accident—for example, when the head or back of a vehicle occupant 16 impacts the component 15 with force in a rear-end collision—causes the resulting energy to be absorbed by the elastic tensioning element 21, thereby reducing the impact. The risk of injury to the vehicle occupant 16 is thus avoided or at least reduced so significantly that there is no risk of injury to the vehicle occupant.The same applies if the airbag moves with sufficient force against component 15 during deployment, causing component 15 to rebound and no further obstruction of the deployment of airbag 11.

[0044] A further advantageous aspect is that, despite the mobility of component 15 described in the last paragraph, it has a mechanically stable attachment with respect to the other spatial directions, in particular away from the seat frame 12. The positive locking effect created by the support sections 25, 26 ensures that component 15 is securely attached to the seat frame 12 with respect to the direction opposite to the suspension travel. This prevents component 15 from detaching in the event of an accident due to the forces acting upon it and from moving rapidly through the occupant compartment 3. Such forces could be caused, for example, by the inertia of component 15 or by the deployment of the airbag 11, which could tear component 15 away.

[0045] Finally, with reference to Fig.Section 4 further explains details regarding the fastening strap 24, by means of which the frame-side cylinder section 23 is attached to the seat frame 12. The fastening strap 24 comprises a metallic strap section 29 that extends along the circumference of a bracket or strut of the seat frame 12 and is attached to the seat frame 12 by means of a positive and / or non-positive connection. The fastening strap 24, or rather the strap section 29, essentially encircles the seat frame 12 according to the principle of a cable tie. A mounting base 30 is attached to the strap section 29, to which the frame-side cylinder section 23 is attached.
