Definitions
- the proposed solution relates to a vehicle seat in which a seat part and a backrest are rigidly coupled to one another.
- Vehicle seats in which a seat part and a backrest are rigidly coupled to one another are widely known from practice.
- a rigid coupling between the backrest and the seat part is provided, for example for reasons of cost and weight, so that a fitting between the seat part and the backrest can be left out.
- the inclination of the seat part and in particular of a seat surface defined on the seat part can therefore no longer be adjusted independently of an inclination of the backrest.
- a sometimes extremely complex and, in particular, crash-sensitive assembly group around a latching or rotary fitting for independent adjustability between the seat part and the backrest is left out. However, this takes place at the expense of not inconsiderable disadvantages in terms of comfort.
- the proposed solution is based on the task of providing a vehicle seat that is improved in this respect and, in particular, that is free of fogging. This object is achieved with a vehicle seat of claim 1.
- a proposed vehicle seat comprises a seat part on which a seat pan part defining a position of a seat surface on the vehicle seat is adjustably arranged.
- the vehicle seat includes a backrest, which is rigidly coupled to the seat part, so that a pivoting movement of the backrest about a rear pivot axis, relative to a longitudinal axis of the seat, via which an inclination of the backrest can be adjusted, always involves a corresponding pivoting movement of the seat part (about the same rear pivot axis) is accompanied.
- a tub adjustment device is provided, via which the seat pan part can be pivoted relative to the seat part about a seat part pivot axis.
- the seat pan part which can be pivoted about an additional seat part pivot axis, allows a seat user to adjust a seat position more specifically and more comfortably, even in a vehicle seat in which the backrest and seat part are rigidly coupled to one another.
- the seat part pivot axis is provided in a rear third of the seat part, based on an extension of the vehicle seat along a seat longitudinal axis.
- the seat part pivot axis for the seat pan part and the rear pivot axis for the backrest can coincide.
- the seat part pivot axis is spaced apart from the rear pivot axis in order to be able to set a support area for a thigh of a seat occupant in its position relative to the backrest in a more targeted manner by adjusting the seat pan part.
- the seat part pivot axis of the seat pan part can coincide with a hip point (in short: H point) specified by the vehicle seat or include the Fl point or be provided only slightly offset from the H point.
- the pan adjustment device can be controlled as a function of a pivoting movement of the backrest for a compensating adjustment of the seat pan part relative to the seat part pivoting with it.
- the compensating adjustment of the seat pan part can be aimed at maintaining (partially or completely) the position of the seat surface assumed before the start of the pivoting movement of the backrest.
- a vehicle seat can therefore, for example, a The seat pan part is adjusted relative to the seat part as a function of a pivoting movement of the backrest, in such a way that when the backrest pivots, the seat part rigidly coupled thereto is also pivoted to the same extent, but the seat pan part is directly related to the pivoting movement of the seat part, i.e.
- a coupling of the tub adjustment device with a device of the vehicle seat for adjusting the inclination of the backrest can consequently be set up to actuate the tub adjustment device to carry out a compensating movement through the seat pan part in order to pivot the seat part (due to the rigid coupling between the backrest and the seat part) at least partially, in particular largely or even completely) to compensate.
- Tub adjustment device and the device for adjusting the inclination of the backrest can be configured in particular that seat pan part to the extent to be adjusted relative to the seat part in which the backrest - together with the seat part - is pivoted about the rear pivot axis.
- the position of the seat surface of the vehicle seat predetermined by the seat pan part is consequently changed by adjusting the seat pan part to the extent relative to the seat part that the backrest is pivoted about the rear pivot axis.
- a device for adjusting the inclination of the backrest can be designed, for example, to implement so-called swing adjustment kinematics.
- the device can then comprise, for example, a two-joint adjuster, ie an adjusting device with adjusting parts adjustable about at least two joint axes for transmitting an adjusting force and for generating the intended adjusting movements.
- a rear pivot axis for pivoting the backrest is understood to mean a pivot axis lying in a transition region between the backrest and the seat part, relative to a longitudinal direction of the seat, so that pivoting about such a (rear) pivot axis causes the backrest to be inclined to specify different usage positions can be adjusted for a seat occupant of the vehicle seat.
- the seat pan part can be pivotable about a further pivot axis.
- the pivot axis for the seat pan part is then arranged, for example, in front of the rear pivot axis for adjusting the inclination of the backrest and thus forms a front pivot axis.
- the pan adjustment device can be used to adjust the seat pan part along a first adjustment direction when the backrest is pivoted in a first pivoting direction about the rear pivot axis, and vice versa along a second adjustment direction when the backrest is pivoted in an opposite second pivoting direction about the rear pivot axis .
- the seat pan part is then raised via the pan adjustment device and inclined toward the backrest when the backrest is pivoted forward in a first pivoting direction.
- the seat pan part is lowered via the pan adjustment device and tilted away from the backrest when the backrest is pivoted backwards.
- the provided coupling between the pan adjustment device and a device of the vehicle seat for adjusting the inclination of the backrest can (also) be mechanical.
- the pan adjustment device comprises at least one drive motor for an externally powered adjustment of the seat pan part and an electronic coupling via control electronics is provided.
- a compensating movement can be implemented comparatively easily and extremely comfortably for a seat occupant via a motorized tub adjustment device and an electronic link between an actuation of the tub adjustment device and an inclination adjustment of the backrest.
- a fog-free vehicle seat can be associated with significant cost advantages, typically requires less installation space and is also easier to install.
- the vehicle seat includes at least one frame part, which forms both part of a backrest frame of the backrest and part of a seat substructure of the seat part.
- the backrest and the seat part can also be designed as separate components or assemblies and only be rigidly fixed to one another, so that a relative movement between the backrest and seat part is not provided.
- additional assembly and cost advantages can be achieved, for example in particular with regard to a one-piece design of a seat part and backrest foam that is then possible more easily and/or Trims for the vehicle seat.
- the vehicle seat includes a one-piece seat frame that forms both the backrest frame and a seat substructure of the seat part that supports the adjustable seat pan part.
- the seat substructure can also have a frame structure to optimize weight.
- the backrest frame and/or the seat substructure are designed as a tubular frame.
- the frame part can also consist of a fiber composite material.
- a seat pan of the vehicle seat can be designed as a full pan or half pan. This is of secondary importance for the advantages that can be achieved with the proposed solution.
- the vehicle seat can additionally include a seat height adjustment device.
- This seat height adjustment device can be coupled electronically and/or mechanically to the tub adjustment device and/or a device in the vehicle seat for adjusting the inclination of the backrest.
- an additional coupling for example via control electronics in a motor-actuated seat height adjustment device, an adjustment of a seat position for a seat user can be set even more finely and to the needs of the seat occupant can be better adjusted.
- the seat height adjustment device is designed with a three-joint adjuster.
- a proposed vehicle seat is designed as a reclining seat and/or as an integral seat with a belt.
- the proposed solution also includes a vehicle with at least one embodiment variant of a proposed vehicle seat.
- Figure 1A shows an embodiment variant of a proposed vehicle seat
- FIG. 1B shows the vehicle seat of FIG. 1A with the seat frame in a rearwardly pivoted second (use) position, with the seat pan part lowered;
- FIGS 2A-2B the vehicle seat of Figures 1A and 1B in reverse order of adjustment.
- the seat frame 10 integrates a backrest frame for a backrest 10R of the vehicle seat 1 and a seat substructure for a seat part 10S of the vehicle seat 1.
- the seat frame 10 is therefore designed in one piece and forms both the backrest 10R and the seat part 10S. Consequently, if the inclination of the backrest 10R of the vehicle seat 1 is to be changed with respect to the horizontal by pivoting the backrest 10R about a rear pivot axis A, the entire seat frame 10 must be pivoted about the rear pivot axis A and perform a rocking movement, with which the Seat part 10S is pivoted.
- the vehicle seat 1 provides a coupling of a frame part adjuster 100 provided for adjusting the inclination of the backrest 10R with a pan adjustment device 20.
- the articulated adjuster 100 can be what is known as a swing adjuster for implementing swing adjustment kinematics.
- the joint adjuster 100 can be designed as a two-joint adjuster.
- a seat pan part 2 mounted pivotably on the seat part 10S about a front seat part pivot axis B (relative to a seat longitudinal axis and the position of the rear pivot axis A) can be adjusted via the pan adjustment device 20 .
- the front seat part pivot axis B for the seat pan part 2 is spaced apart from a seat front and is provided in a rear third of the seat part 10S in relation to a longitudinal seat axis of the vehicle seat 1, so that a front end of the seat pan 2 is raised with respect to the seat part 10S via the pan adjustment device 20 or can be lowered, each changing an inclination of the seat pan part 2 with respect to the seat part 10S. Because a seat cushion of the vehicle seat 1 is arranged or at least supported on the seat pan part 2, the seat pan part 2 ultimately defines the position of the seat surface on the vehicle seat 1.
- the inclination of the seat surface with respect to the horizontal and the backrest R can be adjusted via the tub adjustment device 2 via a motor drive of the tub adjustment device 2 (i.e. independently of an inclination adjustment of the backrest 10R).
- electronic coupling is provided via control electronics 4 between pan adjustment device 20 and frame part adjuster 100, or coupling of the respective motor drives of pan adjusting device 20 and frame part adjuster 100.
- a motor drive of the pan adjustment device 20 is automatically actuated via the electronic control unit 4 to perform a compensating movement if only the inclination of the backrest 10R is to be adjusted and a motor drive of the frame part adjuster 100 is actuated for this purpose.
- the pan adjustment device 20 lowers the seat pan part 2 and thus pivots the front end of the seat pan part 2 in the direction of the seat part pivoted along with the backrest 10R 10S controlled on.
- the seat pan part 2 is consequently pivoted via the pan adjustment device 20 in the opposite direction about the front seat part pivot axis B towards the seat part 10S.
- the backrest 1B can be tilted backwards by a defined amount without the seat surface being pivoted backwards to the same extent for the seat occupant. Rather, the pivoting movement of the backrest 10R is compensated for by lowering the seat pan part 2, so that the alignment of the backrest 10R to the seat surface changes and therefore the thighs of a seat user can remain aligned identically to the seat surface of the vehicle seat 1, although together with the backrest 10R the seat part 10S is also pivoted. As shown in FIG. 1B, the plane of extension R of the backrest 10R then runs at a larger angle ⁇ ( ⁇ > ⁇ ) to the plane of extension S of the seat surface of the vehicle seat 1, since the seat pan part 2 was lowered accordingly.
- ⁇ ⁇ > ⁇
- the electronic control unit 4 consequently controls the pan adjustment device 20 as a function of an adjustment of the seat frame 10 and thus in particular the backrest 10R about the rear pivot axis A, driven by the frame part adjuster 100.
- the electronic control unit 4 thus regulates the pivoting of the seat part 10S and - with a view undesired effects on seating comfort and controls the seat pan part 2 via the pan adjustment device 20 to a compensating adjustment movement if the inclination of the backrest 10R relative to the seat surface of the vehicle seat 1 is to be changed.
- a seat user or another operator who triggers an adjustment on the vehicle seat 1 only has to actuate, for example, one control switch for adjusting the backrest 10R.
- the control electronics 4 automatically takes over the corresponding compensation via the motorized adjustment of the seat pan part 2.
- a seat height adjuster 3 can also be provided on the vehicle seat 1 .
- a seat height of the vehicle seat 1 relative to a vehicle floor can be adjusted via the seat height adjuster 3 .
- the seat height adjuster 3 is coupled to the seat frame 10 which includes the seat part 10S and the backrest 10R and also carries the seat pan part 2 . If the seat frame 10 is consequently shifted via the seat height adjuster 3, the seat height on the vehicle seat 1 changes overall.
- the seat height adjuster 3 is designed as a three-joint adjuster.
- the vehicle seat 1 of FIGS. 1A to 2B is designed without fittings. Consequently, no fitting for changing the relative position between the backrest 10R and the seat part 10S is provided between the backrest 10R and the seat part 10S. Any transmission parts or a transmission shaft for the transmission of an adjustment force between two fittings provided on different longitudinal sides of the seat can thus also be omitted.
- the package advantages that can be achieved in this way are not accompanied by a loss of comfort and a reduction in the possibilities for a seat occupant to adjust their seat position on the vehicle seat 1.
