Definitions

• Vehicle seat in particular motor vehicle seat
• the invention relates to a vehicle seat, in particular a motor vehicle seat, with the features of the preamble of claim 1.
• a vehicle seat of this type is known from EP 1 110 809 A2, in which basic modules are attached to a standard seat frame and / or backrest frame by means of tab-shaped or wire-shaped adapters - without changing the structure - Wear shoulder supports, fans or seat air conditioners.
• the adapters are attached to the frame or nuts fastened to it, for example by means of a screw or rivet connection, the frames being to be weakened as little as possible.
• the invention is based on the object of improving a vehicle seat of the type mentioned. This object is achieved according to the invention by a vehicle seat with the features of claim 1. Advantageous refinements are the subject of the dependent claims.
• the adapter lies flat against the structure with a positive fit, which should be understood to mean that on the one hand the system takes up a considerable part of the facing surfaces of the adapter and the structure (large-area system) and beyond other in this eighty parts of the surfaces facing one another, positive projections and negative depressions of the structure are reciprocated by an inverse contour of the adapter, the possibility of a relative movement between the adapter and the structure is restricted to a few directions without a fixed connection being necessary.
• the possibility of movement is preferably further restricted to the assembly direction, in that the adapter extends between two opposite sides of the structure, for example between two opposite legs of a frame.
• the adapter is the interface between the structure and the upholstery.
• the adapter arranged on the structure serves to shape the upholstery, ie it influences - with its own shape and design - the shape which the upholstery takes on, in particular if the adapter is strongly contoured.
• the adapter is assigned to the cushion and is treated as an integral part of the cushion, for example if it and the cushion are covered with a common cover, the latter preferably extending to the structure.
• the structure gives the adapter the support necessary for the function of shaping the cushion, namely through the system according to the invention.
• the adapter is an advantageous addition to the structure, which enhances the structure in terms of sport, functionality and comfort.
• the adapter is preferably a one-piece component, which preferably consists of a rigid foam, which simplifies production and assembly.
• This design of the adapter is advantageous if the adapter extends in the longitudinal direction of the seat component and laterally shaped material parts with a support function are molded onto the adapter in order to improve the lateral support of the occupant compared to a structure without support elements and to ensure a warp-free assembly compared to welded-on support elements.
• Formative should be understood to mean that the corresponding material section has a significant influence on the shape of the adapter, for example the material section doubles the height of the adapter without material section.
• the material used is advantageous if the adapter is to have a passive crash protection function, according to which the material of the adapter is to absorb and / or dissipate energy in the event of a crash, which increases occupant protection.
• an anti-submarining ramp can be formed on the adapter, which offers a further crash protection function.
• the adapter is preferably also used for arranging, integrating or adapting, in particular storing and / or attaching, individual assemblies to the adapter, in particular cheek adjusters, control devices and cover attachments, suspensions and trackers. stanchions, but also - in the case of the backrest - lumbar supports and / or shoulder incline adjusters and / or - in the case of the seat part - seat extensions.
• the adapter with any modules available upgrades the vehicle seat to a sports seat.
• Show it 1 is an exploded view of a seat cushion of the embodiment
• Fig. 2 is a schematic side view of the embodiment
• Fig. 3 is an exploded view of a backrest of the embodiment.
• a vehicle seat 1 designed as a sports seat for a motor vehicle has, in its seat part 3 defining a first seat component, two pairs of parallel seat rails 5 for longitudinal adjustment, which define the longitudinal direction of the seat, two pairs of rockers 7 articulated on the seat rails 5 for height adjustment and one on the rockers 7 hinged and supported by this seat cushion structure 11, the latter being referred to as a seat frame due to its shape as a circumferential frame with four legs.
• the seat cushion structure 11 carries a one-piece seat cushion adapter 15 made of rigid foam, in particular PUR. Like the seat cushion structure 11, the seat cushion adapter 15 is designed as a circumferential frame. The seat cushion adapter 15 lies flat on the seat cushion structure 11 with a positive fit. As a result, the possibility of a relative movement of the seat cushion adapter 15 and seat cushion structure 11 is restricted, with only the possibility of movement remaining in the mounting direction remaining due to the seat cushion adapter 15 being in contact with all four legs of the seat cushion structure 11. The seat cushion structure 11 remains unchanged during this assembly of the seat cushion adapter 15, in particular without weakening.
• the seat cushion adapter .15 has lateral, raised, shaping material portions 17 in the longitudinal direction of the seat with a support function in order to improve the lateral support of the occupant compared to the relatively flat seat cushion structure 11.
• the seat cushion adapter 15 also has a front, shape-increasing Bende material section 19, which serves as an anti-submarining ramp in the event of a crash.
• the hard foam can absorb and dissipate energy in the event of a crash.
• individual assemblies are arranged, integrated or adapted, in particular stored and / or attached to the seat cushion adapter 15, for example one in the longitudinal direction of the vehicle seat 1 relative to the seat cushion adapter 15, possibly by means of foamed-in rails, longitudinally displaceable seat surface extension 21 and a pair of side cheeks.
• Adjusters 23, which - for example driven by an inflatable bladder - can be pivoted about an axis running at least approximately in the longitudinal direction of the seat, as indicated in the drawing, but only the right one of the two side cheek adjusters 23 is shown.
• Control devices for adjusters or the like can also be attached to the seat cushion adapter 15. Cover hangings, suspensions and trackings can also be integrated in the seat cushion adapter 15, for example adhesive fasteners or receptacles for piping, in particular in the front material section 19 below or behind the seat extension 21.
• a seat cushion pad 25 which is designed in particular as a soft foam part and can overlap the seat cushion adapter 15 completely or partially on the exposed sides.
• a seat cushion cover 27 is pulled over the seat cushion pad 25 and the seat cushion adapter 15 and tensioned, ie fastened to the seat cushion structure 11 and possibly to the seat cushion adapter 15 under pretension. As a result, the seat cushion adapter 15 and the seat cushion structure 11 are held firmly together.
• the seat cushion structure 11, the seat cushion adapter 15, the seat cushion cushion 25, the seat cushion cover 27 and assigned assemblies define the seat cushion.
• the firm cohesion of the seat cushion adapter 15 and the seat cushion structure 11 can additionally be achieved by, for example, a type of snap closure between a material section of the seat cushion adapter 15 and an opening of the seat cushion structure 11 that is present for other reasons, a clamp made of spring steel or another non-positive connection, or a screw connection or the like using existing openings of the seat cushion structure 11, 15 in the seat cushion adapter 15 fasteners such as nuts or the like, but also perforated plates can be foamed.
• the vehicle seat 1 has, as a second seat component, a backrest 30 which can be tilted and pivoted freely, with a backrest structure 32.
• the backrest structure 32 also referred to as the backrest frame, is attached to the rear end of the seat cushion structure 11 by means of two fittings 33 and defines the longitudinal direction of the backrest along its largest dimension.
• one-piece hard foam adapters are also provided here.
• a backrest cheek adapter 34 made of rigid PUR foam is provided in the lower region of the backrest structure 32, of which only the right one is shown in the drawing.
• Each backrest cheek adapter 34 lies flat and with a positive fit on the backrest structure 32.
• the backrest cheek adapter 34 is screwed or otherwise fastened to the backrest structure 32 in order to pass on the forces acting transversely to the backrest longitudinal direction, using an opening there for other reasons. If, in a modified version, the two backrest cheek adapters 34 are connected to one another and there is only one possible movement in the mounting direction, this screwing or other connection can be omitted.
• the backrest cheek adapter 34 has a lateral, raised, shaping material section 36 with a support function in order to improve the lateral support of the occupant in relation to the backrest structure 32.
• the hard foam can absorb and dissipate energy in the event of a crash.
