Definitions
- the invention relates to a device for seat adjustment of a seat, in particular a vehicle seat, and to a mounting assembly for such a device.
- the seat is in particular the seat in a vehicle, in particular a second or third row of seats.
- a foldable seat which has a seat part and a backrest that can be folded down with respect to the seat part.
- the backrest is typically pivotable between two end positions, namely between an upright normal position, also referred to as a comfort position, and a folded folding position, also referred to as a loading floor position. In the folding position, the backrest is often aligned essentially horizontally.
- the backrest is generally pivotally attached via the adjustment mechanism.
- swivel fastening points are provided, which are referred to below as swivel fittings without restricting generality.
- a shaft serves as a drive shaft and also to synchronize the adjustment movement of the two rotating fittings.
- This wave defines a wave axis, which is also regularly a pivot axis.
- the shaft axis is often not fixed but rather performs a typically wobbling movement during the pivoting movement.
- a system for detecting end positions is typically provided to protect the drive motor in order to stop the drive motor in a timely manner and to protect it from overload.
- Such a seat with an electrically adjustable backrest can be seen from DE 10 2004 061 960 A1, in which the end positions are identified by means of two limit switches.
- a spindle with a spindle nut is attached to the shaft.
- the spindle nut has a radially projecting switching cam, which can be translated in translation between two end positions in order to actuate the two oppositely arranged limit switches.
- a headrest is typically attached to the backrest, which is often designed as a foldable headrest. This can be folded down from a normal operating position, in which it is in a position for occupant protection, into a folded position. This folded position is usually assumed in particular in the folding position of the backrest. In the operating position, the headrest is locked and secured using a releasable locking mechanism. In order to fold over into the folded position, the locking mechanism must therefore be released.
- the adjustment mechanism is often complex and elaborate and requires a large amount of space in order to be able to fulfill these different functions.
- the invention is based on the object of enabling seat adjustment, especially an electrically driven, automatic backrest adjustment, with little effort, in a space-saving and cost-effective manner.
- a device for seat adjustment of a seat especially a previously described foldable vehicle seat, which has a seat part and a backrest, which can be adjusted between two end positions, namely between an upright normal position and a folded folding position using an adjustment mechanism.
- the adjustment mechanism in particular has an electric drive motor for automatic adjustment.
- the adjustment mechanism has opposite rotating fittings, via which the backrest is pivotally attached, for example to the seat part or to a holding structure.
- the rotating fittings are connected to one another via a shaft which is rotatable about a shaft axis and extends in the longitudinal direction along the shaft axis.
- the device also has a device for detecting the two end positions, this device having a spindle which is connected to the shaft in a rotationally fixed manner and a spindle nut which is translated in translation when the shaft rotates in the longitudinal direction.
- the spindle nut is part of a driver which has an actuating element for actuating a limit switch.
- the driver is positively guided by means of a mechanical link guide in such a way that a rotary movement is superimposed on the translational movement of the spindle nut and thus of the driver.
- the link guide is designed in such a way that the actuating element actuates the limit switch in both end positions, specifically in such a way that a switching signal is generated when approaching a respective end position.
- Actuating the limit switch is understood here to mean that the actuating element exerts a movement relative to the limit switch, so that it carries out a mechanical actuating movement and in particular is put into a different switching state. For this purpose, the actuating element is either moved away from the limit switch or pressed against the limit switch. Between the two end positions, the limit switch is preferably uninfluenced by the actuating element and is therefore not actuated.
- a particular advantage of this embodiment can be seen in particular in the fact that only a single limit switch is required and provided, which is therefore actuated when one of the two end positions is reached.
- the Actuating element for actuating the limit switch is therefore rotated relative to the limit switch as a result of the superimposed rotary movement in order to thereby actuate it.
- the object is further achieved by a device for seat adjustment of a seat, which in turn can be adjusted between the two end positions using the adjustment mechanism.
- a headrest is attached to the backrest, which can be folded from an operating position into a folded position, the headrest being lockable in the operating position by means of a releasable locking mechanism, so that the headrest is locked in the normal operating position in a particularly crash-safe manner.
- folding the headrest into the folded position is preferably at least supported or carried out using a spring mechanism or a motor drive.
- a driver connected to the shaft which carries out a rotational movement about the shaft axis when the shaft rotates.
- An in particular strand-shaped and preferably bending-flexible control element is attached to the driver, which is connected to the locking mechanism for its actuation, especially for its unlocking, in such a way that when the backrest is adjusted, the locking mechanism is automatically actuated, in particular unlocked, via the control element .
- the control element is displaced and thus exerts an adjusting stroke on the locking mechanism, which releases it.
- the control element exerts a tensile force on the locking mechanism, specifically on a locking or locking element, in order to actuate it.
- the particular advantage of this configuration is that when the backrest is adjusted, any rotation of the shaft that occurs is used to automatically actuate the locking mechanism, thus enabling the headrest to be folded down.
- the actuation of the locking mechanism is therefore positively coupled to the backrest adjustment in a simple manner.
- the spindle already described and connected to the shaft is preferably provided and the driver has the spindle nut already mentioned, which is translated in a translational manner when the shaft rotates in the longitudinal direction.
- the driver is positively guided by means of the link guide to generate its rotational movement.
- the special advantage of the link guide is that the rotary movement and the required adjustment stroke are controlled in a targeted manner.
- the link guide or link control therefore causes the locking mechanism to be actuated at a defined pivoting position of the backrest with respect to the seat part.
- the locking mechanism is actuated at the beginning of the pivoting movement of the backrest from the normal position towards the folding position.
- these two previously described aspects are combined with one another. Due to the special design of the driver, which carries out a translational and a rotational movement via the rotary movement of the shaft, two different functions, namely the actuation of the limit switch on the one hand and the actuation (unlocking) of the locking mechanism of the headrest on the one hand, are coordinated by a common mechanism and executed. This results in a particularly compact design with few components, which overall leads to a cost-effective solution.
- the control element preferably has a rope, a wire or a plastic strand as a strand-shaped element and is also preferably designed as a Bowden cable.
- the control element is designed to transmit both tensile forces and compressive forces to the locking mechanism.
- the link guide is generally designed in such a way that during the translational movement of the driver in the longitudinal direction, i.e. in only one direction, the driver itself moves in different directions Directions of rotation are operated. This results in targeted control in and against a defined direction of rotation around the shaft axis.
- This achieves a controlled rotational movement of the actuating element for actuating the limit switch in the first aspect of the invention and for generating a controlled and defined actuating stroke in different directions in the second aspect of the invention.
- the link guide therefore ensures that when the backrest is pivoted in only one direction, the actuating element and/or the control element itself execute different and, in particular, opposite movements. This ensures that in the first aspect the actuating element can only operate one limit switch, which is preferably designed as a button, in both end positions.
- the link guide is designed in particular in such a way that during the translational movement in the longitudinal direction, i.e. H. in only one direction, starting from the first end position of the backrest (normal position) in a starting area, the driver rotates in one direction of rotation and that in the area of the second end position of the backrest (folding position) the driver rotates in an end area of the translational movement in the opposite direction to the direction of rotation.
- the driver moves generally in the longitudinal direction along the spindle from a first end position in the start region to a second end position in the end region.
- the start and end of the translational movement are defined by the two end positions of the backrest, to which the two end positions of the driver correlate.
- the limit switch is actuated for the first time by the rotational movement in the direction of rotation via the actuating element, which is preferably designed as a button.
- the actuating element is rotated away from the limit switch and thus away from the button. This means that the button is moved from a previously pressed position to a relieved, released position in which the actuating element is removed.
- the limit switch is actuated again by the actuating element due to the opposite rotation.
- the button is pressed, i.e. that the actuating element is rotated towards the button and thereby generates a switching signal which signals that the (second) end position has been reached.
- This switching signal is detected by a suitable electronic control and in particular leads to the stopping of an electric drive motor.
- the movement sequences are described below, starting from the upright normal position towards the folded position.
- the entire adjustment mechanism is designed in such a way that during the opposite movement, i.e. when unfolding from the folding position into the normal position, the movement sequences are in opposite directions and take place in the reverse order.
- control element in the starting area the control element is loaded and in particular tensioned by the rotational movement in the direction of rotation, so that the control element carries out the control stroke for actuating the locking mechanism.
- control element In the end region, the control element is relieved, in particular relaxed again, by the counter-rotating movement.
- a middle area is provided, which is formed between the start area and the end area.
- the limit switch is not activated in this middle area.
- the link guide is therefore designed in such a way that the functional state of the actuating element and/or the control element is maintained.
- the control element preferably remains in the tensioned state in the middle area.
- the central region extends, for example, over at least 40% and preferably over at least 50% of a total translational adjustment path of the driver along the spindle.
- the length of the starting area in the longitudinal direction corresponds, for example, to a maximum of 30% and in particular a maximum of 20% of the length of the entire translational adjustment path.
- the length of the end region preferably also corresponds to a maximum of 30% and in particular a maximum of 20% of the length of the entire translational adjustment path.
- the length of the end area and the start area are preferably identical.
- the control element or the actuating element is held in a quasi-neutral position in which there is no change in its state, specifically no triggering of a function, such as the actuation of the limit switch or the control element.
- the actuating element is held at a distance from the limit switch.
- the control element is held in the center area in the loaded position, i.e. the tensioned position.
- the link guide has sections with different gradients relative to the shaft axis, so that - depending on its translational position along the spindle - the driver has different rotational speeds and / or different directions of rotation.
- the driver expediently has a sleeve-shaped part with an internal thread to form the spindle nut, with one or more and preferably all of the elements listed below being formed on the circumference of the sleeve-shaped part:
- a holder, in particular a nipple holder for an end piece, is preferably provided specifically for a nipple of the control element.
- the actuating element is designed to be elongated in the longitudinal direction and preferably as a rib oriented in the longitudinal direction.
- the length of the actuating element in the longitudinal direction corresponds in particular at least to the translational adjustment path of the driver between its two end positions. This reliably ensures that the actuating element actuates the (only) limit switch in the two end positions through the rotary movement in or against the direction of rotation.
- this can also be composed of two sections spaced apart from one another in the longitudinal direction, which are positioned in such a way that they are in the respective end position at the length position of the limit switch.
- a guide element designed in particular as a guide pin is arranged on the sleeve-shaped part, which protrudes in the radial direction and engages positively in the link guide.
- the driver is preferably designed as a one-piece, monolithic component and consists, for example, of plastic.
- the component is produced, for example, as a cast part, injection molded part or using a 3D printing process.
- a support component is also provided, which is in particular firmly connected to the backrest and which has the link guide and a bearing for the spindle.
- This support component is in particular a component of a complete assembly assembly, which can be attached to the seat, especially to the backrest.
- the carrier component preferably has at least one and preferably several and in particular all of the following elements: At least one and preferably several fastening elements for fastening the carrier component to Seat and especially on the backrest.
- fastening elements for fastening the carrier component to Seat and especially on the backrest.
- latching or plug-in elements are provided.
- screw fastening elements are provided, for example.
- a guide for the control element is formed on the carrier component.
- This guide is in particular a channel that is open to one side, for example, and into which the control element, especially the Bowden cable, can be inserted.
- the carrier component preferably also has a holder for an electronic assembly, the electronic assembly in turn comprising the limit switch. This defines the position of the limit switch on the carrier component and therefore also in relation to the spindle and thus to the driver.
- the carrier component is preferably a one-piece, monolithic component, in particular made of plastic.
- the carrier component is produced, for example, as a cast part, injection molded part or by a 3D printing process.
- This assembly assembly has the previously described support component, the spindle and the driver.
- the link guide is integrated into the support component.
- the spindle is rotatably mounted on the bearing, for example a plain bearing.
- the spindle is generally preferably hollow and designed to insert the shaft through and to be connected to the shaft in a rotationally fixed manner.
- the non-rotatable connection is formed, for example, by a frictional connection between the shaft and spindle.
- a positive connection is preferably formed between the shaft and the spindle.
- the guide element for engaging in the link guide is arranged on the driver and finally the actuating element for the limit switch and/or the holder for the end piece of the control element is arranged.
- This assembly assembly forms a pre-assembled unit that only needs to be attached to the seat and especially to the backrest.
- FIG. 1 shows a seat in a perspective view with a backrest in an upright normal position and a dashed view of the backrest in a folding position
- FIG. 2 shows a perspective view of a mounting assembly
- FIG. 6A shows a sectional view along the section line EE in FIG. 5,
- FIG. 6B shows a sectional view along the section line B - B in FIG. 5 as well
- 6C shows a sectional view along the section line C - C in FIG.
- a seat 2 shown in FIG. 1 is intended as a vehicle seat for installation in a vehicle. It has a seat part 4 and a backrest 6, which can be pivoted and folded relative to the seat part 4 from an upright normal position into a folded folding position. The seat part 4 and the backrest 6 in the folded position are shown in dashed lines.
- two opposite swivel fittings 8 are provided, which in the exemplary embodiment are attached to two opposite fastening structures, to which the seat part 4 is also attached and via which attachment to a vehicle floor takes place.
- the two rotating fittings 8 are connected to one another via a shaft 10, which extends along a shaft axis 12 in a longitudinal direction L.
- the shaft 10 is designed as a drive shaft for adjusting the inclination of the backrest 6 and is not provided here electric drive motor shown in more detail.
- the shaft 10 also serves to synchronize the movement of the two opposing rotating fittings 8.
- a foldable headrest 14 is also attached to the backrest 6 and can be folded from a normal operating position into a folded position.
- the headrest 14 In the normal operating position, the headrest 14 is oriented essentially in the direction of the backrest 6 (right half of the picture in FIG. 1 with the backrest 6 in the upright normal position) and in the folded position essentially transversely to the backrest 6 (left half of the picture, dashed representation of the backrest 6 and the headrest 14 in the folding position).
- the position of the headrest 14 can be locked in the operating position by means of a locking mechanism 16.
- a control element 18 is provided, which in the exemplary embodiment is designed as a Bowden cable.
- the headrest 14 is usually preloaded by means of a spring mechanism, so that when the lock is released it automatically folds over into the folded position due to the spring force.
- the rotating fittings 8, the shaft 10, the locking mechanism 16, the control element 18 and the electric drive motor are parts of an adjustment mechanism for the electric motor-controlled adjustment of the backrest 6.
- the positions of the backrest 6 shown in FIG. 1, namely the upright normal position and the folded folding position form final positions.
- the adjustment mechanism generally has a device for detecting these two end positions, which emits a signal to the motor control when the end positions are reached, so that the drive motor is stopped. While the backrest 6 is folded down, the lock of the locking mechanism 16 is automatically released and the headrest 14 folds down into the folded position.
- a particularly pre-assembled assembly assembly 20 is specifically provided for this purpose, which is shown in FIG. 1 with the dashed circle is marked. It is preferably arranged immediately adjacent to one of the rotating fittings 8, in the exemplary embodiment to the rotating fitting 8 on the left half of the picture.
- the structure and function of the assembly assembly 20 can be seen in particular from the following figures. 2 shows the assembled assembly assembly 20 and the individual elements of the assembly assembly 20 can be clearly seen based on the exploded view according to FIG.
- the individual elements are arranged individually on a backrest structure, for example.
- the following description of the interaction of the individual elements applies equally to such a fastening and is independent of the design of the pre-assembled assembly.
- the assembly assembly 20 has a support component 22, which is designed in particular as a monolithic component, for example as an injection molded part.
- the assembly assembly 20 has a spindle 24, which is designed as a hollow cylindrical element.
- the shaft 10 is inserted through the spindle 24 and connected to it in a rotationally fixed manner.
- the shaft 10 in the exemplary embodiment has a non-round cross-sectional geometry and is, for example, designed as a polygon at least in the area of the spindle 24.
- a driver 26 is attached to the spindle 24, which is preferably also designed as a monolithic, one-piece component, for example as an injection molded part.
- the driver 26 has a sleeve-shaped part 28, which carries an internal thread, not shown here, which is in engagement with the external thread of the spindle 24, so that when the shaft 10 rotates and the associated rotation of the spindle 24, the driver 26 in or . is translationally offset against the longitudinal direction L.
- the sleeve-shaped part 28 thus forms a spindle nut.
- the actuating element 30 extends generally in the longitudinal direction L and is in particular designed in the manner of a radially projecting web or a rib.
- the holder 34 has a slotted hollow channel, which is designed in particular as a so-called nipple holder chamber.
- nipple holder chamber In this there is a form-fitting nipple, which is attached at the end to a cable of the control element 18 designed as a Bowden cable (see also FIG. 3).
- a guide element designed as a guide pin 38 is also arranged on the circumference, which protrudes in the radial direction.
- a cap 40 is attached to this, which is designed in the manner of a so-called roller cap in order to ensure the lowest possible friction during operation (FIG 3).
- the carrier component 22 also has a holder 42 (FIG 3) which accommodates an electronic assembly 44 which includes the previously mentioned limit switch 32.
- the electronic assembly 44 is essentially the limit switch 32 and a plug connected to it.
- the limit switch 32 is connected to a control unit via an electrical plug connection.
- the limit switch 32 is designed as a button.
- the carrier component 22 further has a guide 46 designed in the manner of a guide channel, in particular in an upper end region, in which the control element 18 is received and held, in particular in a form-fitting manner.
- control element 18 is designed in particular as a Bowden cable, which generally has a rope or a wire which is guided within a hose-like sheath.
- the nipple is typically attached to the end of the rope (compare specifically FIG. 3).
- An end piece of the casing is now preferably held in a form-fitting manner in the guide 26.
- Link guide 48 preferably as a channel-like recess within the Carrier component is formed, which has a defined 2-dimensional course (FIG 3).
- the carrier component 22 has a bearing 50, which is designed in particular in the manner of a plain bearing, and in which an end piece of the sleeve-shaped spindle 24 is rotatably mounted (FIG 3).
- the bearing 50 and the end piece of the spindle 24 are generally preferably used for both radial and axial fixation of the spindle 24 on the carrier component 22.
- the end piece initially has a sleeve-shaped web which engages in the bearing 20 for radial storage.
- a rib-like web is formed around the running and radially projecting web, which is provided for axial fixation and rests on a corresponding annular wall of the support component 22.
- Fastening elements 52 which are preferably designed as locking elements, are also formed on the support component 22.
- the carrier component 22 and thus the entire assembly assembly 20 are attached to the backrest 6 via this.
- the guide pin 38 engages in the link guide 48.
- the translational movement of the driver 26 is therefore superimposed on a rotational movement, which is defined and controlled by the link guide 48.
- the driver 26 is in a first end position, which corresponds to the first end positions and thus the upright normal position of the backrest 6.
- the spindle 24 rotates and leads to the translational movement of the driver 26 in the longitudinal direction L.
- the driver 26 passes through a middle area (FIG. 4B) and finally reaches one End area and reaches a second end position (FIG 4C). This second end position corresponds to the second end position of the backrest 6, when it is in the folding position.
- the end of the initial range is defined by the maximum rotational deflection in the direction of rotation D.
- this rotational movement tensions the control element 18 and tightens it by a defined adjustment stroke, which leads to the unlocking of the locking mechanism 16.
- the functional positions of the actuating element 30 and the control element 18 remain at least essentially unchanged. This means that the actuating element 30 continues to remain in its position lifted from the limit switch 32 and the control element 18 remains in its cocked position.
- link guide 48 This is expressed in the case of the link guide 48 in particular in the fact that, viewed in the longitudinal direction L, it initially rises steeply up to a maximum lateral deflection transversely to the longitudinal direction L, in order to then fall again with a smaller gradient.
- the driver 26 is finally rotated back essentially back into the rotational position that it assumed at the beginning, i.e. in the first end position.
- the actuating element 30 is rotated again against the limit switch 32 and actuates it, which is evaluated by the control unit as a switching signal for reaching the second end position.
- control element 18 In the second end position, the control element 18 is still relieved, i.e. H. there is no longer any tensile stress.
- the movement sequence is in opposite directions, i.e. H. the driver 26 starts from its second end position in FIG. 4C and moves towards its first end position in FIG. 4A.
- the actuating element 30 is first lifted from the limit switch 32, then passes through the middle area in this lifted rotational position, in order to then be rotated again in the initial area towards the limit switch 32 and actuate it.
- a switching signal to stop the electric motor is generated.
- FIGS. 6A to 6C show a sectional view in the first end position, i.e. at the beginning of the adjustment movement and at the beginning of the rotational movement from the first end position.
- 6C shows a sectional view at the maximum rotational deflection of the driver 26 and thus this sectional view according to FIG. 6C defines the end of the initial area. Based on FIG. 6C it can be clearly seen how the limit switch 32 (button) is released by the actuating element 30 and that the control element 18 is also tightened by an adjusting stroke.
