Definitions
- Vehicle seats in vehicles usually have several seat components, in particular a seat cushion (seat upholstery), possibly with laterally molded side bolsters, and a seat back or backrest (back upholstery), possibly with laterally molded side bolsters.
- a seat cushion seat upholstery
- back upholstery seat back or backrest
- the seat components of the vehicle seat often also have a load-bearing structure as a support structure.
- a seat device for a vehicle in which side support sections of the seat device can be predictively moved inwards and outwards by a drive depending on the course of the road.
- DE 102007 009 891 A1 describes an adjustment device for adjusting a side bolster of a seat.
- This adjustment device comprises an adjustment element to be coupled to the side bolster, support means for mechanically supporting the adjustment element and an inflatable bladder for positioning the adjustment element relative to the support means when adjusting the side bolster.
- DE 102014210 790 A1 describes a vehicle seat assembly with a cushion pad that can be folded for entering and exiting the vehicle.
- the cushion pad extends laterally from either a seat base or a backrest of the vehicle seat and has a cushion support with a hinge arrangement, an abutment element and an engagement surface arranged therebetween.
- a spring-loaded dynamic element coupled to either the backrest or the seat base can be moved to a folded position for entering and exiting the vehicle.
- a motor vehicle seat which has adjustable side bolsters on the seat part and/or on the backrest. The length and the orientation of the side bolsters in relation to the central seat area and/or the backrest area can be changed by combined adjustment of the side bolsters, in particular with the aid of a combined linear and rotary guide, in order to generate a controlled track movement.
- the generic JP 2005206 027 A further shows a vehicle seat with at least one seat component, which has a supporting structure and two side parts formed on a seat surface, wherein the at least one seat component has a width adjustment mechanism for adjusting the width of the seat surface of the seat component and an angle adjustment mechanism coupled to the width adjustment mechanism for adjusting the angle of at least one side part of the seat component, wherein the width adjustment mechanism of the respective seat component has two cross strut pairs arranged at a distance from one another and connected to the supporting structure of the seat component, each with two cross struts, wherein a rigid part of a respective cross strut is connected to the supporting structure of the seat component and a movable part of a respective cross strut that can be moved by a certain travel path is connected to one of the two side parts of the seat component, and that the movable part of the respective cross strut has a joint that is connected to a rigid part of the respective cross strut to form the angle adjustment mechanism when the cross strut is moved. deflection
- the invention is based on the object of specifying a vehicle seat in which a support function and/or holding function for a vehicle occupant located on the vehicle seat is realized in a simple manner with advantageous properties.
- a change in the width of the seat surface of certain seat components of the vehicle seat is realized by means of a preferably electric motor-operated width adjustment mechanism by narrowing or widening the seat surface (often also referred to as the seat mirror), which is located between two side parts of the respective seat component.
- a change in the width of the seat surface of the seat cushion of the vehicle seat, which has two molded-on side cheeks, is carried out by narrowing or widening the seat surface of the seat cushion and/or a change in the width of the seat surface of the seat back of the vehicle seat, which has two molded-on side cheeks, is carried out by narrowing or widening the seat surface of the seat back.
- This width adjustment mechanism for adjusting the width of the seat surface of the respective seat component is coupled to an angle adjustment mechanism, by means of which the angle of at least one side part formed on the seat surface of the respective seat component can be adjusted by means of a folding mechanism.
- the width adjustment mechanism of the seat surface of the respective seat component is coupled to the angle adjustment mechanism or folding mechanism for the two side parts of the respective seat component via a positive guide.
- This angle adjustment mechanism or folding mechanism for folding the two side parts of a seat component only becomes effective when a certain dimension is exceeded when adjusting the width of the seat surface of the respective seat component, i.e. the angle adjustment mechanism for folding the two side parts of a seat component is only initiated when a certain travel distance is exceeded when adjusting the width of the seat surface of the respective seat component.
- the width adjustment mechanism of the respective seat component has two pairs of cross struts, each with two cross struts, arranged at a distance from one another and connected to the supporting structure of the seat component.
- the cross struts are connected to the supporting structure of the seat component with a rigid part and to one of the two side parts of the seat component with a movable part that can be moved by a certain travel path.
- two cross struts are connected to the one connected to the side part of the seat component molded onto the seat surface of the seat component and two cross struts are connected to the other side part of the seat component molded onto the seat surface of the seat component.
- the movable part of the respective cross strut has a joint designed, for example, as a swivel joint or hinge joint, which cooperates with a deflection element attached to the rigid part of the respective cross strut to form the angle adjustment mechanism when the movable part of the respective cross strut is moved.
- the angle adjustment mechanism is initiated and a folding process of the respective side part of the seat component is started when the joint attached to the movable part of the respective cross strut has arrived at a deflection position corresponding to a characteristic travel path of the movable part of the respective cross strut, at which position the deflection element is arranged on the rigid part of the respective cross strut.
- this deflection position is determined and fixed by positioning the deflection element on the rigid part of the respective cross strut in such a way that the angle adjustment mechanism is initiated and the folding process of the respective side part of the seat component is started when the travel path of the movable part of the respective cross strut corresponds to one third of the total possible travel path of the movable part of the respective cross strut. Accordingly, on one third of the total possible travel path of the movable part of the respective cross strut, a pure width adjustment or enlargement of the respective seat component takes place, i.e.
- the angle of the two side parts of the respective seat component may also be changed.
- the close contact between the body of a vehicle occupant sitting on the vehicle seat and the respective seat component also improves the heat transfer from a seat heater provided for the respective seat component to the vehicle occupant, thereby increasing the efficiency of the seat heater.
- the positions or angles set by adjusting the width of the respective seat component and the angle of the two side parts of the respective seat component remain until a different position or angle is specified by subsequent activation of the width adjustment mechanism.
- these side parts of the seat component are then folded away or folded back in the opposite way to the folding process of the side parts of the respective seat component when the side parts of the seat component are folded in.
- the respective seat component preferably has two longitudinal struts arranged on one half of the seat of the respective seat component and several elastic tensioning elements with a certain elasticity that are oriented parallel to the respective cross struts of the cross strut pairs and are designed in particular as springs.
- These elastic tensioning elements are connected at one end to a longitudinal strut that is connected to the rigid part of the cross struts and thus cannot be moved, and at the other end to a longitudinal strut that is connected to the movable part of the cross struts or to a longitudinal strut that forms the outer contour of the side part of the seat component and is therefore foldable.
- the elastic tensioning elements are provided on each seat half of the respective seat component, for example three or four springs with a defined spring strength distributed equidistantly on each seat half of the respective seat component.
- the elastic tensioning elements also form support points or support surfaces for the seat cushion of the respective seat component, for example by means of springs as elastic tensioning elements, so that no separate spring basket is required for the respective seat component.
- the elasticity of the elastic tensioning elements, in particular the spring constant of elastic tensioning elements designed as springs is selected so that they have predetermined properties with regard to seating comfort and angle adjustment. In particular, this sets a certain seat softness for the respective seat component of the vehicle seat and a certain hardness for the implementation of the folding process of the two side parts of the respective seat component of the vehicle seat.
- These elastic tensioning elements which are designed in particular as springs, thus ensure on the one hand that a type of pincer movement takes place when the two side parts of the seat component of the vehicle seat are folded in, so that a vehicle occupant sitting on the vehicle seat is virtually clamped by the two folded-in side parts.
- these elastic tensioning elements which are designed as springs, ensure a certain softness of the seat cushion of the respective seat component of the vehicle seat and form a corresponding support surface for the seat cushion of the respective seat component of the vehicle seat.
- At least one such elastic tensioning element in particular at least one elastic tensioning element designed as a spring, is also arranged between the two longitudinal struts connected to the rigid part of the cross struts of a pair of cross struts, i.e. to the two longitudinal struts arranged adjacent to one another on each seat half of the seat component.
- an electric motor-driven adjustment drive for moving the movable part of the two cross struts of the respective cross strut pair is integrated into the width adjustment mechanism in each of the two cross strut pairs.
- These two electric motor adjustment drives which are arranged centrally in the respective seat component, are thus used to change the width of the respective Seat component by narrowing or widening the seating area of the respective seat component of the vehicle seat.
- an electric motor with differential is provided in the respective adjustment drive.
- the adjustment drive can have a movable spindle as a spindle drive, possibly also a gear unit with gears and a braking device.
- the adjustment drive is used to move the movable parts of the cross struts of the respective seat components simultaneously and in the same direction.
- the braking device can be used to control this movement of the movable parts of the cross struts on the two seat halves of the seat component of the vehicle seat.
- both side cheeks of the seat cushion of the vehicle seat or both side bolsters of the seat back of the vehicle seat are folded in at the same time.
- the seat component of the vehicle seat has an elastic material which is deformable in accordance with this movement of the seat surface of the seat component.
- the seat surface of the respective seat component of the vehicle seat in particular the seat surface of the seat cushion of the vehicle seat and/or the seat surface of the seat back of the vehicle seat, preferably consists of an elastic material that deforms according to the travel path of the movable parts of the cross struts.
- the elastic material of the seat surface of the respective seat component of the vehicle seat therefore also follows the change in width of the seat surface of the seat component of the vehicle seat by narrowing or widening the seat surface of the seat component of the vehicle seat and accordingly the movement of the seat surface of the seat component of the vehicle seat.
- the activation of the width adjustment mechanism and thus possibly also of the angle adjustment mechanism dependent on it can be carried out in a manual mode by a vehicle occupant sitting on the vehicle seat by operating a control element.
- This control element can be designed, for example, as a switch or a button or a push-button, by operating which the vehicle occupant can individually adjust the width of the seat surface of the respective seat component of the vehicle seat and the angle position of the side parts on both sides of the respective seat component of the vehicle seat.
- the activation of the width adjustment mechanism and thus, if applicable, also of the angle adjustment mechanism dependent on it is specified automatically, in particular by controlling a control unit of the vehicle connected to the vehicle seat.
- the automatic activation of the width adjustment mechanism and thus, if applicable, also of the angle adjustment mechanism dependent on it takes place in particular as a function of acceleration forces acting on the vehicle and thus on the vehicle seat.
- the respective width adjustment mechanism is controlled for the simultaneous and co-directional change in the length of the two cross struts of the frame-shaped support structure of the seat component.
- the width adjustment of the respective seat component i.e.
- a length adjustment mechanism can also be integrated in the two side parts of the seat component of the vehicle seat, in particular in the two side cheeks of the seat cushion of the vehicle seat and/or in the two side bolsters of the seat back of the vehicle seat.
- This length adjustment mechanism in the two side parts of the seat component of the vehicle seat is provided for the simultaneous and identical height adjustment of the two side parts of the seat component of the vehicle seat, in particular for the simultaneous and identical height adjustment of the two side cheeks of the seat cushion of the vehicle seat and/or the two side bolsters of the seat back of the vehicle seat, and thus enables (height) adjustment of the seat component of the vehicle seat to the body size of a vehicle occupant sitting on the vehicle seat.
- the respective length adjustment mechanism can have an electric motor integrated into the side part of the seat component of the vehicle seat or connected to the side part of the seat component of the vehicle seat for adjustment.
- the vehicle seat can be designed for any vehicle, in particular for autonomously driving vehicles in which the vehicle occupants can adopt variable seating positions in the vehicle during autonomous ferry operation,
- a simple device enables a rapid change in the width of the seat surface of a seat component and a change in angle coupled thereto and thus a folding of the two side parts of the respective seat component, in particular a rapid change in the width of the seat surface of the seat cushion of the vehicle seat and/or the seat surface of the seat back of the vehicle seat and a change in angle coupled thereto and thus a folding of the side cheeks of the seat cushion of the vehicle seat and/or the side cheeks of the seat back of the vehicle seat.
- This active embracing of a vehicle occupant sitting on the vehicle seat by folding the two side parts of the seat components of the vehicle seat is particularly advantageous as crash preparation in the event of an impending collision of the vehicle and also offers good lateral support for vehicle occupants sitting on the vehicle seats in autonomous ferry operation of autonomously driving vehicles. Furthermore, in a vehicle seat with seat heating, the heat transfer from the vehicle seat to the vehicle occupant is effective, so that only a low heating output is required for the seat heating.

- Fig. 2 A section of the backrest support structure of the seat back of a vehicle seat with a detailed view of the width adjustment mechanism and the angle adjustment mechanism in a retracted position.
- FIG. 3 A section of the backrest support structure of the seat back of a vehicle seat with a detailed view of the width adjustment mechanism and the angle adjustment mechanism in an extended position.
- Fig. 4 A schematic representation of the seat cushion and the backrest support structure of the seat back of a vehicle seat.
- the vehicle seat 1 has, as seat components 2, in addition to the seat cushion (not shown), a seat back 2 or backrest with two side bolsters 5, 6 formed laterally onto the seat surface 4 of the seat back 2.
- a side bolster 5 on one seat half 17 of the seat back 2 is formed onto the seat surface 4 of the seat back 2 and a side bolster 6 on the other seat half 18 of the seat back 2 is formed onto the seat surface 4 of the seat back 2.
- a backrest support structure 3 is integrated into the seat back 2 or backrest of the vehicle seat 1 to stabilize the structure of the vehicle seat 1 or the seat back 2.
- cross struts 9, 10 arranged at a distance from one another are provided, each with two cross struts 11.
- the cross struts 11 have a rigid part 12 with a derailleur attached to a specific deflection position as a deflection element 15 and a movable part 13 with a hinge 14 that can be moved along a specific travel path.
- a width adjustment mechanism 7 is integrated in the middle of each of the two cross strut pairs 9, 10, i.e. in the upper cross strut pair 9 with the respective two cross struts 11 in the upper area of the backrest support structure 3, and in the lower cross strut pair 10 with the respective two cross struts 11 in the lower area of the backrest support structure 3.
- This width adjustment mechanism 7 can be used to move or move the movable parts 13 of the cross struts 11 of the cross strut pairs 9, 10 and thus to move the movable parts 13 of the cross struts 11 on both sides from the outside to the inside in the direction of the middle of the seat back 2 of the vehicle seat 1 or from the inside to the outside in the direction of the respective side bolster 5, 6 of the seat back 2 of the vehicle seat 1.
- This also adjusts the width of the seat between the two side bolsters 5, 6.
- the seat surface 4 located on the seat back 2 of the vehicle seat 1 is changed in its width, ie the seat back 2 of the vehicle seat 1 is thereby narrowed or widened.
- Figure 1 shows the situation in which the movable parts 13 of all cross struts 11 of the two cross strut pairs 9, 10 have been moved by a specific travel path from the inside to the outside in the direction of the respective side bolsters 5, 6 of the seat back 2 of the vehicle seat 1, i.e. are in an extended position.
- an angle adjustment mechanism 8 becomes effective, which causes the two side cheeks 5, 6 of the seat back 2 of the vehicle seat 1 to fold.
- This angle adjustment mechanism 8 is caused by the movement of the hinge 14 on the movable part 13 in interaction with the deflection on the unwinder or derailleur as deflection element 15 and due to the spring tension of several springs as elastic tensioning elements 16 tensioned between the rigid longitudinal struts 19 and the movable longitudinal struts 20 forming the outer contour of the two side cheeks 5, 6 of the seat back 2 of the vehicle seat 1.
- three such springs are provided as elastic tensioning elements 16 on each seat half 17, 18 of the seat back 2 of the vehicle seat 1 between the rigid longitudinal struts 19 and the movable longitudinal struts 20.
- a spring 22 of this type can be arranged as an elastic tensioning element between the two rigid longitudinal struts 19.
- the sleeves 28 are provided in the frame of the backrest support structure 3.
- an adjustment drive 23 with an electric motor 24 and spindle drives 25 arranged centrally in the respective cross strut pair 9, 10 is provided for each cross strut pair 9, 10.
- a corresponding length adjustment mechanism 26 can be provided for adjusting the height of the two side bolsters 5, 6 of the seat back 2 of the vehicle seat 1.
- the two side bolsters 5, 6 of the seat back 2 of the vehicle seat 1 can be adjusted in height simultaneously and in the same direction.
- Figure 2 shows a detailed view of the fully retracted state of the movable parts 13 of the respective cross struts 11.
- the springs as elastic tensioning elements 16 are pre-tensioned in this position of the fully retracted state for the next extension of the movable parts 13 of the cross struts 11.
