Definitions
- the invention relates to a seat substructure for a seat or a single seat in a motor vehicle, in particular a motorhome, with a frame for a seat cover and connecting means for fastening the frame to the vehicle floor.
- seat substructures are usually used, which show a variety of adjustment options.
- the seat substructure can allow the seat to be arranged in the direction of travel or opposite to the direction of travel in the vehicle.
- the seat substructure is displaceable in the longitudinal direction of the vehicle and can be locked in different positions or can be removed from the rear of the vehicle.
- the seat substructures are type-specific in length and seat depth and width so that they can be used in the respective motor vehicle.
- the known seat substructures are generally made from welded individual parts, in particular rods. Different dimensions must be selected for different vehicle types. In addition to a high workload, this requires the storage of different component types in large numbers.
- the object of the invention is to provide a seat substructure of the type mentioned at the outset which can be assembled in a simple manner with the aid of the same components for different types of vehicles.
- This object is achieved according to the invention in that the frame has two vertical support plates which extend in the longitudinal direction of the vehicle and have a substantially continuous and force-absorbing vertical sheet surface, which are connected on their upper sides to further frame parts which extend transversely to the longitudinal direction of the vehicle and have fastening means on their underside , which can be adapted to the respective floor anchoring means of different vehicle types and that the support plates have angled surfaces to which the frame parts extending transversely to the vehicle longitudinal direction and the fastening means are fastened.
- the vertical support plates preferably each have a continuous sheet surface, so that the support plate is rigid in the plane of this surface. If there are recesses or openings in the surface, these are dimensioned and arranged so that the rigid design of the support plate is maintained in its vertical surface.
- the transverse frame parts which are preferably designed as 90 ° angle profiles and are each attached to two bevels arranged at right angles to one another or otherwise angled to at least three fastening points, the result is a frame which is rigid in all directions and above which the vehicle seat or the vehicle seat is supported on the vehicle floor.
- the space between the two support plates can be used as an uninterrupted storage space. It is not necessary that diagonal cross struts or the like are provided in this space.
- the frame parts extending transversely to the longitudinal direction of the vehicle lie flat against the folds or the angled surfaces and, as already stated, are fastened to the folds at several points.
- two fastening points can be provided on one fold, for example by means of screw connections, and at least one fastening point, in particular a screw connection, can be provided on the other fold at a 90 ° angle.
- the support plates and the frame parts which are preferably designed as 90 ° angle profiles, can thus be used as starting components for different-sized benches and vehicle seats.
- the support plates can be designed symmetrically with respect to a horizontal and / or vertical center plane, so that they can be used both on the left and on the right side of the seat. It is therefore sufficient to have a type of support plate ready for the manufacture of the seat substructure.
- the upper and lower folds can have recesses at their respective ends, the required fastening means being provided on the respective folds lying at the bottom in the region of the two recesses and adapted to the respective floor anchoring means of the different vehicle types.
- Fastening points for one or more seat belts can also be provided on the frame.
- the fastening means which are preferably fastened to the front and rear ends of the respective support plate, can be designed, for example, for a locked engagement with a mushroom head anchorage with detachable locking.
- the fastening means can be designed as sliders, which are guided displaceably in floor rails anchored to the vehicle.
- a releasable locking mechanism can be provided for fixing the vehicle seat or the vehicle bench in different positions in the vehicle along the floor rails.
- the respective fastening means can have one or more bores through which an anchoring bolt fastened to the vehicle can optionally be inserted with a thread for fastening the seat in the vehicle with the aid of a screw connection.
- the recess provided at the front and at the rear end of a respective bevel enables the arrangement of anchoring bolts and bolts as well as similar components which serve to fasten and lock the seat substructure on the vehicle floor.
