Description

Technical Field

[0001] The invention relates to an armrest device for a seat, in particular a vehicle seat, and a seat, in particular a vehicle seat, having such an armrest device. Background Art

[0002] Generally, for example height-adjustable, in particular foldable or pivotable armrests are known from the prior art. Summary of the invention

[0003] Purpose

[0004] The object of the present invention is to improve an armrest of the initially mentioned type, in particular with regard to increasing the adjustability and providing a corresponding vehicle seat.

[0005] Solution

[0006] According to the invention, the first object is achieved by an armrest arrangement having the features specified in claim 1. According to the invention, the second object is achieved by a seat, in particular a vehicle seat, having the features specified in claim 10 .

[0007] The armrest arrangement according to the invention comprises at least one armrest having an armrest rail arrangement which is configured for longitudinally adjusting the armrest in a translational manner from a base position to an extended position, wherein the armrest rail arrangement comprises at least one fixed armrest rail and an armrest rail which is movable, in particular longitudinally adjustable, relative to the fixed armrest rail, and a gear unit, and wherein the armrest rail arrangement is arranged on the armrest relative to the longitudinal direction such that a drive interface of the gear unit is oriented downwards or upwards, for example in the direction towards a vehicle seat, or inwards, for example in the direction towards a vehicle seat, in particular a seat structure of a vehicle seat, or in an intermediate position.

[0008] By such an orientation of the drive interface of the gear unit, the armrest drive unit can be arranged outside the armrest, for example on the vehicle seat, in particular underneath the vehicle seat, or on a long side of the vehicle seat.

[0009] In other words, the handrail comprises only a handrail rail arrangement and a gear unit, which can be connected to a handrail drive unit, for example a motorized handrail drive unit with a flexible output shaft, via a drive interface. The handrail rail arrangement can, for example, be rotated about a longitudinal axis. In this way, the drive interface, in particular the flexible shaft interface (also referred to as flexible shaft input), can be arranged to be more downwards than directly inwards. The handrail rail arrangement can, for example, be rotated through a region of 30° to 90° or up to 180°. When rotating by 90° or 180°, the drive interface for connecting to the flexible output shaft of the handrail drive unit points directly downwards. The handrail rail arrangement can also be oriented to be mirrored with respect to a horizontal plane or in the vertical.

[0010] The handrail rail arrangement may be oriented parallel to a horizontal plane.

[0011] Alternatively, the handrail guide arrangement is oriented to rotate about a longitudinal axis.The handrail guide arrangement is oriented to tilt about a horizontal plane.

[0012] The handrail guide arrangement may be provided on an underside of the handrail opposite the arm support surface.

[0013] The handrail guide arrangement may be arranged and fastened inside the handrail, for example inside the handrail bracket and / or the handrail pad. Thus, a compact and visually improved handrail may be provided.

[0014] A plurality of functional modules may be arranged in a cavity of the handrail located above the handrail guide rail arrangement.

[0015] The plurality of functional modules can include at least a table, a beverage holder, a control unit and / or an adjustment switch for longitudinal adjustment of the armrest.

[0016] The handrail rail arrangement may comprise a handrail drive unit, which may be coupled or coupleable to the gear unit via a drive interface.

[0017] The handrail drive unit can be arranged below the handrail guide rail arrangement or in its region and can be coupled to the gear unit via a flexible drive shaft or via a flexible drive shaft. In this way, the handrail can be provided with only the handrail guide rail and the gear unit and be compactly formed.

[0018] A seat according to the invention, in particular a vehicle seat, comprises at least one armrest having an armrest guide rail arrangement as described above, which is configured for translational longitudinal adjustment of the armrest from a base position into an extended position. Preferably, on each seat side, the vehicle seat comprises such an armrest and an armrest drive unit, which is arranged below the seat structure and from which at least one flexible output shaft originates, which can be coupled or is coupled to a gear unit of the armrest. In the case of two armrests, two flexible output shafts are provided, which can be coupled or are coupled to two gear units and each originates from an end of the armrest drive unit, which is in particular arranged in the middle or in the center. The respective output shaft can be in an arcuate form or can be coupled in an arcuate form to one of the gear units.

[0019] The armrest arrangement may comprise two armrests, each of which may be provided with an armrest rail arrangement, wherein an armrest drive unit of the armrest rail arrangement may be arranged below the seat structure of the seat cushion or in the region of it. The armrest drive unit may have a flexible drive shaft on both sides, in particular at the respective ends, wherein the respective flexible drive shaft may be coupled or may be coupled to an associated gear unit of the respective handrail rail arrangement. In this way, only one drive unit is provided to actuate both handrail rail arrangements, thereby saving installation space and costs.

[0020] Therefore, the armrests are equipped with a longitudinal adjustment function, which can adjust both armrests at the same time. This enables convenient entry and exit functions ("welcome" function, "farewell" function), in which, for example, the armrest slides back 150 mm to make it easier to enter and exit the seat. If the seat is, for example, moved fully forward to allow access to the rear seat, the adjustable armrest can avoid a collision with the center console, in which the entry dimensions can be easily increased. In addition, when the occupant is in a reclining position, the armrest can move backwards to follow the occupant's torso as it moves into the reclining position.

[0021] The gear unit can be configured, for example, as a spindle gear with a spindle and a spindle nut. The spindle is fixedly connected to the movable handrail rail. The spindle nut is movably, in particular rotatably, mounted in the fixed handrail rail. The fixed handrail rail can, for example, be arranged and fastened to a seat structure, in particular a backrest structure or a seat cushion structure, and / or to a bracket fixed to a floor. The spindle is axially movably mounted via the spindle nut. The spindle thus carries, together with the spindle nut, the handrail fixedly connected thereto. At least one flexible output shaft can be directly coupled to the spindle nut. Alternatively, the flexible output shaft can be coupled to a drive screw, which in turn drives the spindle nut.

[0076] Positional and directional terms used, such as radial, axial, and circumferential, are relative to the rotational axis 108 of the control assembly 106. Radial means perpendicular to the rotational axis 108. Axial means along or parallel to the rotational axis 108.

[0077] The vehicle seat 100 may optionally include a longitudinal adjustment device 110. The longitudinal adjustment device 110 comprises, for example, a track arrangement 112 having a first track element 114 and a second track element 116. The first track element 114 is adjustable in the longitudinal direction x relative to the second track element 116. The first track element 114 is attached to the seat cushion 102. The second track element 116 is attached to a structural element of the vehicle, such as a vehicle floor 118 (e.g., Figure 4 shown).

[0078] For greater clarity, the first rail element 114 is referred to in the following description as a top rail 114. The top rail 114 (also referred to as a running rail or a slide rail) is assigned to the vehicle seat 100 and is configured to carry the vehicle seat 100. The second rail element 116 is referred to hereinafter as a lower rail 116. The lower rail 116 is fixed and connected, for example, to the floor of the vehicle.

[0079] Furthermore, the vehicle seat 100 comprises at least one armrest 120 (also referred to as longitudinally adjustable or axially adjustable armrest 120 ), which is adjustable in a longitudinal direction x along an arrow 122 and will be described in greater detail below.

[0080] The armrest 120 extends substantially in a longitudinal direction x. Depending on the equipment level, when the armrest 120 is viewed in a vertical direction Z, the armrest 120 comprises at least an arm supporting surface 124 .
