Description

The invention relates to a vehicle seat with an adjustable armrest and armrest kinematics.

Armrest devices for adjusting armrests of vehicle seats with manual adjustment or with a drive device are known. The publications are representative as the starting point of the invention DE 10 2005 061 982 B4 , DE 10 2006 011 994 A1 , DE 10 2008 010 605 A1 , DE 10 2018 207 036 A1 and the pamphlet DE 10 2020 110 364 A1 called.

Proceeding from these known technical solutions, the object of the invention is to enable a comfortable ergonomic adjustment of the armrest position as a function of the seat height and backrest adjustment. In a front or rear seat, i.e. a vehicle seat in general, when an armrest is arranged - on the door side - and to reach vehicle seats in the middle position also - on the inside of the vehicle -, there is also the need to lower or swivel away the armrest to enable and exit.

The starting point of the invention is a vehicle seat with an adjustable armrest.

Provision is made for an adjustment mechanism to be arranged by means of joints between a seat part of the vehicle seat that can be adjusted in height and/or inclination and an inclination-adjustable backrest of the vehicle seat, with the adjustment mechanism comprising a structural element on the seat part side and a structural element on the backrest side with electrically controllable drives assigned to them, each of which is actuated at the end by means of of a central joint are rotatably connected to one another, and the respective other end is connected to the seat part by means of a joint on the seat part or to the backrest by means of a joint on the backrest, with the structural element on the backrest carrying the armrest.

According to the invention, it is provided that each structural element comprises a receiving element and a guide element, the electrically controllable drive unit assigned to each structural element providing an actuation action for actuating the respective receiving element relative to the respective guide element. The actuating action is brought about by means of an actuating element which is assigned to each drive unit and which drives the drive units electrically.

The actuating elements are preferably adjustment switches.

Provision is preferably made for the receiving element and the guide element of the structural elements to be arranged in a translationally movable manner relative to one another in an uninhibited state.

Provision is preferably made for the electrically controllable drive units to be integrated into the structural elements and the actuating elements, in particular the adjustment switches, into the armrest.

This structural configuration advantageously creates armrest kinematics for a vehicle seat with an adjustable armrest, which enables the following functions:

• Armrest kinematics for "individual armrest position adjustment":
  1. 1. By exclusively actuating at least one of the electrically controllable drive units of the adjustment mechanism, an individual armrest position adjustment of the armrest is brought about if only at least one of the structural elements is adjusted in its length.
• Armrest kinematics for "automatic armrest position adjustment":
  • 2. Without actuating the electrically controllable drive units, an automatic armrest position adjustment of the armrest is effected if only the seat part and/or the backrest are actuated.
• Armrest kinematics for setting an "EASY-EXIT position" of the armrest:
  • 3A Without actuating the electrically controllable drive units to make it easier for a person to sit on and off the side, the armrest is in an “EASY-EXIT position”, in which the armrest and the adjustment mechanism assume a lowered position if only the seat part 12 and/or the Backrest 14 are operated.
  • 3B. By exclusively actuating at least one of the electrically controllable drive units of the adjustment mechanism, the "EASY-EXIT position" of the armrest is brought about to make it easier for a person to sit on and off the side, in which the armrest and the adjustment mechanism assume a recessed position when using the drive units only at least one of the structural elements is adjusted in its length.
  • 3AB. By actuating at least one of the electrically controllable drive unit of the adjustment mechanism, an "EASY-EXIT position" of the armrest is brought about to make it easier for a person to sit on and off the side, in which the armrest and the adjustment mechanism assume a recessed position when the seat part and/or or the backrest is actuated and the length of at least one of the structural elements is adjusted by means of the drive units.

The invention is explained below with reference to the accompanying drawings. Show it:

the 1 and 2 show a vehicle seat 100 in a perspective view obliquely from the front and in a side view with an armrest 10 (in a sectional view) and an adjustment mechanism 20 assigned to the armrest 10 (in a sectional view) and a side view, with a seat part 12 and a backrest 14 are arranged in a normal position and the armrest 10 in a first position I. This first position I of the armrest 10 and the normal position of the seat part 12 and the backrest 14 are also referred to as the starting position of the vehicle seat 100 to explain the invention.

the 1 and 2 are explained below in a synopsis.

The armrest 10 is arranged on a first structural element 21 of the adjustment mechanism 20 .

The first structural element 21 comprises a receiving element 21A and a guide element 21B, with the receiving element 21A receiving the guide element 21B in a longitudinally displaceable manner, with the receiving element 21A being fixed relative to the guide element 21B as soon as an electrically driven drive unit 21C is in a state that inhibits an adjustment. In other words, the guide element 21B can be longitudinally displaced relative to the receiving element 21A by means of the drive unit 21C as soon as the drive unit 21C is actuated.

The drive unit 21C is integrated into the first structural element 21, which is used to adjust the position of the armrest 10, independently of the inclination adjustment of the backrest 14 relative to the seat part 12, and is also referred to as the backrest-side drive unit 21C in the longitudinal direction x, since by means of the drive unit 21C the position of the armrest 10 relative to the backrest 14 in the x-direction can be adjusted essentially forwards and backwards.

To actuate the drive unit 21C, an actuating element, in particular an adjustment switch (not shown), is arranged, which when actuated causes the receiving element 21A to be blocked/unblocked and adjusted relative to the guide element 21B by means of the first drive unit 21C. This means that the guide element 21B can be unlocked relative to the receiving element 21A and, in the uninhibited state, can be adjusted in one direction in the one adjustment direction +x when the adjustment switch is actuated, and in the other direction in the other adjustment direction -x when the adjustment switch is actuated .

It goes without saying that the actuating element, i.e. the adjustment switch electrically connected to the drive unit 21C (possibly via a control unit) can also be arranged elsewhere on the vehicle seat 100 or in the interior of the vehicle without being integrated into the armrest, but it is placed in the armrest 10 integrated adjustment switches represent the preferred variant.

According to the invention, the adjusting mechanism 20 comprises a further second structural element 24 which is assigned its own drive unit 24C, with the second drive unit 24C also preferably being integrated into the armrest 10 .

The second drive unit 24C is used to adjust the position of the armrest 10, regardless of the height adjustment of the seat part 12 relative to the backrest 14, and is also used as a seat part-side drive unit 24C in the height direction z referred to, since the position of the armrest 10 relative to the backrest 14 in the z-direction can be adjusted essentially up and down by means of the drive unit 24C.

How from the 1 and 2 When viewed together, it becomes clear that the first structural element 21 is connected to the other, second structural element 24 in an articulated manner via their receiving elements 21A, 24A.

As the figures also illustrate, the other second structural element 24 comprises the receiving element 24A and the guide element 24B, with the receiving element 24A also receiving the guide element 24B in a longitudinally displaceable manner, with the receiving element 24A being fixed relative to the guide element 24B as soon as the drive unit 24C is in the inhibiting position locked state. In other words, the guide member 24B is longitudinally displaceable relative to the receiving member 24A as soon as the drive unit 24C is actuated.

To actuate the drive unit 24C, a separate actuating element (also not shown), in particular also an adjustment switch, is provided, which when actuated causes locking and unlocking (by inhibiting/uninhibiting the drives 21C, 24C) and adjustment of the receiving element 24A relative to the guide element 24B by means of of the first drive unit 21C is effected.

That is, the guide element 21B can be locked and unlocked relative to the receiving element 21A and in the uninhibited state, and when the adjustment switch is actuated in one direction, in one adjustment direction +z, and when the adjustment switch is actuated in the other direction, in the other direction Adjustment direction -z adjustable.

The structural elements 21, 24, in particular their receiving elements 21A, 24A, are connected to one another via a central joint 2124, so that the structural elements 21, 24 can be pivoted relative to one another about a y-axis Y2124, which runs into the plane of the page. The y-axis Y2124 is parallel to the usual pivot axis (no reference number) of the backrest 14 opposite the seat part 12.

The armrest 10 is rotatably connected on the one hand via the first structural element 21, in particular the guide element 21B, to a structural part of the backrest 14, in particular the backrest frame 14A, via a joint 2114 on the backrest.

On the other hand, the armrest 10 is rotatably connected via the second structural element 24, in particular the guide element 24B, to a structural part of the seat part 12, in particular to a seat part upper frame 12B, which is height-adjustable relative to the seat part frame 12A, of the seat part frame 12A in a fixed position via a joint 1224 on the seat part side.

The armrest 10 is pivotally connected to the back frame 14A of the backrest 14 via the backrest-side joint 2114, whereby the armrest 10 placed on the first structural member 21 is adjustable as the first structural member 21 moves.

In other words, the armrest 10 follows the position of the first structural element 21.

If the structural element 21 is lowered or raised, the armrest 10 is also lowered or raised.

If the angle of inclination of the structural element 21 relative to an imaginary horizontal x/y plane changes, the inclined position of the armrest 10 relative to the imaginary horizontal x/y plane is also correspondingly changed.

The following functions can be designed by this structural solution of the adjustment mechanism 20 in connection with the arrangement of the armrest 10.

First function:

The seat part 12 can be adjusted by adjusting the height and/or inclination of the seat part upper frame 12B in relation to the seat part frame 12A (cf 1 until 4 ) tilt-adjustable, height-adjustable or height-adjustable in the z-direction, this adjustment being regarded as a height adjustment in the z-direction to simplify the description.

The backrest 14 can also be tilted (cf 1 until 4 ) adjustable, this adjustment being regarded as a longitudinal adjustment in the x-direction to simplify the description, since the armrest 10 pivots essentially in the x-direction in the longitudinal direction x.

In the 1 and 2 the vehicle seat 100 with the armrest 10 (as a sectional view) and the adjustment mechanism 20 associated with the armrest 10 (also as a sectional view) in perspective ( 1 ) and in a side view ( 2 ) is shown with the seat portion upper frame 12B of the seat portion 12 and backrest 14 in the normal position and the armrest 10 in 3 in a second position II and in 4 are arranged in a third position III, which will be discussed below.

When the height of the seat part 12 and/or the inclination of the backrest 14 is adjusted, there is an automatic "armrest adjustment function" according to the invention, in which, in addition to the adjustment of the position of the seat part 12 and/or the backrest 14, without any action, i.e. without a separate operator action of the user, at the same time the location / position of the armrest 10 is adjusted.

The adjustment takes place by means of the joints 1224, 2124 and 2114 without the drive unit 21C on the backrest side and the drive unit 24C on the seat part side having to be unlocked/disinhibited and actuated.

An automatic adjustment of the position of the armrest 10 thus results - without actuating the drive units 21C and 24C when adjusting the height of the seat part 12 and/or the inclination adjustment of the backrest 14, always depending on the starting position I of the armrest 10 (e.g. first position of the armrest 10 according to the 1 and 2 ) of the seat part-side and backrest-side joints 1224 and 2114.

The automatic adjustment of the position of the armrest 10 takes place based on the position of the armrest 10, which the user has previously selected by means of the drive units 21C and/or 24C in by individually changing the position of the receiving elements 24A, 21A relative to the guide elements 24B, 21B. where the second function is seen.

Second function:

Starting from the initial position, for example the first position I of the armrest, the user can 1 , the position of the structural elements 21, 24 relative to one another in each position of the seat part 12 and/or the backrest 14 can be changed individually by the user actuating at least one drive unit 21C, 24C.

As a result, the central joint 2124 (independent of a movement of the seat part 12 and/or the backrest 14) can be adjusted individually, downwards or upwards, with the guide elements 21B, 24B being displaced relative to the receiving elements 21A, 24A and pivot about the joints 1224 and 2114 with respect to the seat part upper frame 12B and the backrest frame 14A.

Third function:

For entry and exit, i.e. the easier "entry and exit function", also called "EASY-EXIT function", the armrest 10 is unlocked/disinhibited in one embodiment (with actuation of the drive units 21C, 24C) via the adjustment switch , whereby the drive unit 21C on the backrest side and the drive unit 24C on the seat part side move to the “EASY-EXIT position” II according to FIG 3 be driven.

The position of the armrest 10 can be changed without moving the seat part 12 and/or the backrest 14 (cf 2 and 3 ) can be changed/adjusted to make it easier for a person to get into the optimal position for this, since the guide elements 21B and 24B can be adjusted relative to the receiving elements 21A and 24A.

Actuation of the drive units 21C, 24C results in the central joint 2124 (regardless of a movement of the seat part 12 and/or the backrest 14) being inclined downwards (compare again 2 and 3 ) can be adjusted while the guide elements 21B and 24B pivot about the joints 1224 and 2114 in relation to the seat part upper frame 12B and the backrest frame 14A. This solves the object of the invention, which is looking for a convenient solution to make it easier for a person to get in and out.

It goes without saying that getting in and out becomes easier if the joints 1224 and 2114 (cf 4 ) before actuation of the drive units 21C, 24C are already in a position that is as low as possible in relation to the imaginary x/y plane.

For example, the vehicle seat 100 may be in a lying position in which the joints 1224 and 2114 (cf 4 ), before the actuation of the drive unit, are already in a position that is as low as possible in relation to the imaginary x/y plane. Actuation of the drive units 21C, 24C causes the central joint 2124 (independent of a movement of the seat part 12 and/or the backrest 14) to move even further - than in 3 is shown - can be adjusted obliquely downwards by pivoting the guide elements 21B and 24B relative to the seat part upper frame 12B and the backrest frame about the joints 1224 and 2114.

In another embodiment variant (without actuating the drive units 21C, 24C), the procedure is as follows: For entry and exit, that is, the facilitated “EASY-EXIT function”, who the drive units 21C, 24C are not actuated, for this purpose the seat part upper frame 12B is moved downwards and/or the backrest frame 14A backwards until the structural elements 21, 24, and therefore the joints, 1224, 2124, 2114 are stretched in a line (analogous to to 3 ) lie, whereby an “EASY-EXIT position” can be set depending on the previously set position of the guide elements 21B and 24B relative to the receiving elements 21A and 24A.

• - die Antriebseinheiten 21C, 24 betätigt werden, da sich die Führungselemente 21B und 24B relativ zu den Aufnahmeelementen 21A und 24A verstellen lassen, und
• - der Sitzteiloberrahmen 12B soweit nach unten und/oder der Lehnenrahmen 14A so weit nach hinten gefahren wird, bis die Strukturelemente 21, 24, mithin die Gelenke, 1224, 2124, 2114 gestreckt auf einer Linie (Kombination der 3 und 4) liegen.

The two variants can be combined with one another in a third variant if

• - the drive units 21C, 24 are actuated, since the guide elements 21B and 24B can be displaced relative to the receiving elements 21A and 24A, and
• - the upper seat part frame 12B is moved downwards and/or the backrest frame 14A backwards until the structural elements 21, 24, and therefore the joints, 1224, 2124, 2114 are stretched out on a line (combination of 3 and 4 ) lie.

• - durch Betätigung mindestens einer der Antriebseinheiten 21C, 24C des Verstellmechanismus 20 eine erste Funktion, als „individuelle Armlehnen-Anpassungsfunktion“ geschaffen, wenn Sitzteil 12 und Rückenlehne 14 unbetätigt sind, und
• - ohne Betätigung der Antriebseinheiten 21C, 24C des Verstellmechanismus 20 eine zweite Funktion, als „automatische Armlehnen-Anpassungsfunktion“ geschaffen, wenn Sitzteil 12 und/oder Rückenlehne 14 betätigt werden, und
• - ohne Betätigung der Antriebseinheiten 21C, 24C des Verstellmechanismus 20 (in einer ersten Ausführungsvariante) eine dritte Funktion als „EASY-EXIT-Funktion“ geschaffen, wenn das Sitzteil 12 und/oder die Rückenlehne 14 (nach unten beziehungsweise nach hinten) betätigt werden, und
• - mit Betätigung der Antriebseinheit 21C, 24C des Verstellmechanismus 20 (in einer zweiten Ausführungsvariante) die dritte Funktion als „EASY-EXIT-Funktion“ geschaffen, wenn das Sitzteil 12 und/oder die Rückenlehne 14 nicht betätigt werden, und dafür die Strukturelemente 21, 24 derart in ihrer Länge verstellt werden, sodass das Zentral-Gelenk 2124 in seine tiefste Position kommt, und
• - mit Betätigung der Antriebseinheiten 21C, 24C des Verstellmechanismus 20 (in einer dritten Ausführungsvariante) die dritte Funktion als „EASY-EXIT-Funktion“ geschaffen, wenn das Sitzteil 12 und/oder die Rückenlehne 14 (nach unten beziehungsweise nach hinten) betätigt werden und die Strukturelemente 21, 24 über die Antriebseinheiten 21C, 24C derart in ihrer Länge verstellt werden, sodass das Zentral-Gelenk 2124 in seine tiefste Position kommt.

It is thus

• - By actuating at least one of the drive units 21C, 24C of the adjustment mechanism 20, a first function created as an "individual armrest adjustment function" when the seat part 12 and backrest 14 are not actuated, and
• - without actuating the drive units 21C, 24C of the adjustment mechanism 20, a second function created as an "automatic armrest adjustment function" when the seat part 12 and/or backrest 14 are actuated, and
• - Without activating the drive units 21C, 24C of the adjusting mechanism 20 (in a first embodiment variant), a third function is created as an “EASY-EXIT function” when the seat part 12 and/or the backrest 14 are actuated (downwards or backwards), and
• - With actuation of the drive unit 21C, 24C of the adjustment mechanism 20 (in a second embodiment variant), the third function is created as an "EASY-EXIT function" if the seat part 12 and/or the backrest 14 are not actuated, and the structural elements 21 for this, 24 are adjusted in length so that the central joint 2124 comes to its lowest position, and
• - With actuation of the drive units 21C, 24C of the adjustment mechanism 20 (in a third embodiment variant), the third function is created as an "EASY-EXIT function" if the seat part 12 and/or the backrest 14 are actuated (downwards or backwards) and the length of the structural elements 21, 24 can be adjusted via the drive units 21C, 24C in such a way that the central joint 2124 comes into its lowest position.
