Description

Technical Field

[0001] This utility model relates to a handrail having a base and an arm resting component, the arm resting component being pivotally supported about a pivot axis formed by the base. Background Technology

[0002] This armrest structure is designed for installation on a vehicle seat. Vehicle seats typically include a padded seat structure. The seat structure includes a support for the mounting structure of the armrest base. A problem with existing seats is that the seat pads have large tolerances, and therefore the distance between the armrest and the seat pad is undefined. For example, the armrest contacts the pad, and the armrest rubs against the seat pad during pivoting. Alternatively, an excessively large gap between the armrest and the pad is undesirable for visual reasons. Utility Model Content

[0003] The purpose of this invention is to provide an armrest that forms a defined gap between the padding and the armrest.

[0004] This objective is achieved by a handrail having the features of this invention.

[0005] An armrest for a vehicle seat includes a base and an arm rest pivotable about a pivot axis relative to the base between a first position and a second position. The base includes a mounting mechanism capable of engaging a seat structure of the vehicle seat and a shaft mechanism forming a pivot support with the arm rest. The seat structure is padded. A connector cap is fixed to the base coaxial with the pivot axis and at a distance defined from the side of the arm rest facing the padded axis. The connector cap extends in a plane perpendicular to the pivot axis and forms an extension boundary for the padded axis in a direction parallel to the pivot axis.

[0006] The armrest structure according to this utility model is for mounting on a vehicle seat. The armrest includes a base and an arm rest portion pivotable about a pivot axis relative to the base between a first position and a second position. The base has a mounting mechanism that engages with the seat structure of the vehicle seat (e.g., with a support). Furthermore, the base includes a shaft mechanism that forms a pivot support with the arm rest portion. The seat structure is padded.

[0007] A connector cover (hinged cover) is fixed to the base at a distance defined coaxially with the pivot axis from the side of the arm rest facing the liner (which may be formed, for example, by the housing). The connector cover extends in a plane perpendicular to the pivot axis. The connector cover forms an extension boundary for the liner in a direction parallel to the pivot axis.

[0008] This creates a defined gap between the connector cover and the armrest of the handrail. The padding does not rub against the movable armrest and therefore wears less. The handrail appears to be of higher quality because it does not have areas where the padding is not defined.

[0009] The connector cover is constructed, for example, as a disc. It has, for example, a surface extending in a direction perpendicular to the pivot axis. The extent of the extension of the connector cover's surface is adapted, for example, to the area of ​​the vehicle seat cushion and armrest that are opposite each other when the armrest moves. The disc can be, for example, circular, elliptical, or polygonal. The disc can be, for example, flat or arched. Regarding the shape, it depends, for example, on fit, i.e., forming a barrier for the seat cushion in the direction of extension toward the armrest.

[0010] The connector cover extends radially, for example, about the centerline or the pivot axis of the armrest. Because the armrest pivots about the pivot axis, the seat cushion and the armrest are opposite each other in a region extending radially about the pivot axis. Therefore, the connector cover restricts the seat cushion in this region.

[0011] The connector cover is constructed, for example, as an annular disc. In the radially inner region, it is passed through, for example, by a shaft mechanism that forms a pivot for the arm rest.

[0012] The mounting mechanism may include, for example, a fixing mechanism by which the armrest can be releasably fixed to the seat structure. The fixing mechanism may include, for example, a threaded fixing part by which the armrest can be threadedly connected to the seat structure. The fixing mechanism may also include, for example, a flange.

[0013] For example, an alignment mechanism (such as a centering mechanism) serving as an installation mechanism is constructed on the base and can engage with a corresponding alignment mechanism to more easily position the fixing mechanism in the correct location during installation. The centering mechanism is, for example, formed by a pin. This pin, for example, has a shape-locking mechanism to prevent torsion. It can, for example, engage with a complementary structure. Through the alignment mechanism, the handrail can, for example, be positioned in the x / z plane.

[0014] The mounting mechanism, for example, includes a stop mechanism that determines the position of the armrest relative to the seat structure in a direction parallel to the pivot axis. The position of the armrest can be positioned, for example, relative to the y-direction. The stop mechanism is, for example, provided to a flange. For example, when the stop mechanism contacts the corresponding surface of the vehicle seat structure, the base is arranged in the seat of the vehicle seat structure.

[0015] Stopping mechanisms and / or fixing mechanisms, for example, are provided to flanges.

[0016] Mounting mechanisms and / or shaft mechanisms are, for example, provided to a retaining member on which the arm rest is supported. The connector cover may also be supported directly or indirectly on the shaft member. The shaft member may directly constitute the pivot of the arm rest. Alternatively, the shaft member holds at least one additional component constituting the pivot.

[0017] For example, the distance between the stop mechanism and the shielding surface of the connector cover away from the armrest is fixed. In this case, the seat cushion always has a defined gap in the direction parallel to the pivot axis with respect to its extension to the armrest. The seat cushion may rest against the side of the connector cover or extend within the gap. However, it cannot extend into the joint gap between the connector cover and the armrest.

[0018] The connector cap may be formed of, for example, plastic or metal. In principle, any material suitable for forming a barrier for the gasket is suitable as a material for the connector cap. The material and shape of the connector cap must be suitable for preventing the gasket from extending in the relevant surface area, particularly in critical areas, in a direction parallel to the pivot axis.

[0019] The connector cover, for example, has a fixing area through which it can be fixed to the base. If the connector cover is formed, for example, of a plate-like member, it is advantageous to manufacture it separately and then fix it to the handrail member. For this purpose, the connector cover, for example, has a fixing mechanism. These fixing mechanisms are constructed in suitable positions. The fixing mechanisms are constructed, for example, on the plate-like area of ​​the connector cover or on a separate fixing area. If the connector cover is constructed, for example, of a ring-like member, the fixing mechanisms are arranged, for example, on the inner area of ​​the ring.

[0020] The circumferential surface of the connector cover, coaxial with its central axis, forms a gap with, for example, the inner wall surface of the opening in the arm rest housing. When the arm rest moves between a first and a second position, the inner wall surface moves relative to the circumferential surface. In this case, the connector cover also helps to provide visual obstruction for the joint between the arm rest and the base.

[0021] Alternatively, the connector cover may be integrally formed with a component of the base, for example.

[0022] Advantageously, the connector cover is at least partially constructed as a disc or plate.

[0023] Advantageously, the connector cover extends radially relative to the pivot axis of the arm rest.

[0024] Advantageously, the connector cover is constructed as an annular disc.

[0025] Advantageously, the mounting mechanism has a fixing mechanism by which the base can be releasably fixed to the seat structure.

[0026] Advantageously, the mounting mechanism has a stop mechanism that determines the position of the armrest relative to the seat structure in a direction parallel to the pivot axis.

[0027] Advantageously, a stop mechanism and / or a fixing mechanism are provided to the flange.

[0028] Advantageously, the flange and shaft mechanism are provided for the retaining components.

[0029] Advantageously, the distance between the shielding surface of the stop mechanism and the connector cover away from the arm rest is determined.

[0030] Advantageously, the connector cover is made of plastic or metal.

[0031] Advantageously, the connector cover has a fixing area through which the connector cover can be fixed to the base.

[0032] Advantageously, the circumferential surface of the connector cover, which is coaxial with the central axis of the connector cover, forms a gap with the side wall of the opening of the housing of the arm rest.

[0044] The handrail as a whole is indicated by reference numeral 1 in the figure.

[0045] exist Figure 1 The base 11 and armrest 12 of the armrest 10 can be seen, the armrest having an armrest surface 42. The base 11 includes a mounting mechanism 13 configured to secure the armrest, particularly to secure the base to a vehicle seat (not shown). The mounting mechanism 13 includes a pin 14 with ribs 17 for centering and anti-torsion, and a flange 15. The pin 14, extending in a direction parallel to the y-axis, can be mounted with its ribs 17 in a complementary receiving portion of the structure of the vehicle seat (not shown). The pin 14 forms a centering portion that guides the fixing mechanism 30 of the base 11 into the correct position. In this example, the pivot axis a of the armrest 12 coincides with the central axis of the pin 14.

[0046] The flange 15 forms a stop mechanism in the form of a stop face 19 and has a fixing mechanism 30, which is formed in the form of an opening 18 through which a screw 24 passes, connecting to the structural thread of the vehicle seat. Here, the screw is only shown as a dashed line. However, any suitable fixing mechanism can be used alternatively. The armrest 10 is fixed in the y-direction by the stop mechanism and fixed in the x and z directions by the centering part and the fixing mechanism 30, and held in its rated position.

[0047] Furthermore, the retaining mechanism 16 of the base 11 can be seen, which constitutes the support area 35 for the arm rest 12. In this example, the integral retaining member 32 includes a portion of the mounting mechanism 13 and a portion of the retaining mechanism 16. The retaining member 32 constitutes the pin 14, the flange 15, and the support area 35.

[0048] exist Figure 1The connector cover 20 can also be seen. In this example, the connector cover 20 is constructed as an annular disc that extends radially to the pivot axis a. The central axis of the connector cover 20 coincides with the pivot axis a in this example. In this invention, the shape of the annular disc is not crucial. Other shapes of covers that prevent the padding from extending in the direction of the arm rest 12 can also be used in this invention.

[0049] After the flange 15 is secured to the structure of the vehicle seat, the edge area of ​​the opening in the gasket 23 and the cover overlaps the flange and tightens behind the rear side 33 of the flange 15, so that the edge rests against the outer surface 34 of the shaft mechanism 16. In other words, an area of ​​the gasket 23 is arranged between the flange 15 and the shielding surface 21 of the connector cover 20.

[0050] according to Figure 1 and Figure 2 The arm rest 12 is arranged in a primary position, in which its longitudinal central axis m is arranged, for example, approximately horizontally. The arm rest 12 can pivot relative to the base 11 about a pivot axis a from the primary position through an intermediate position to... Figure 6 and Figure 7 In the secondary position shown. According to an alternative embodiment, the arm rest 12 may also occupy an additional position. For example, the arm rest 12 may pivot such that the longitudinal axis m is arranged substantially vertically or even pivoted beyond the vertical position, wherein the longitudinal axis m forms an obtuse angle with the horizontal position.

[0051] according to Figure 3 A constant gap l1 is formed between the outer surface 33 of the flange 15 and the shielding surface 21 of the connector cover 20. A constant gap l2 is formed between the rear surface 41 opposite to the shielding surface 21 and the side surface 22 of the housing 28 of the arm rest 12. A boundary area of ​​the gasket 23 is indicated by reference numeral 40. The gasket 23 of the vehicle seat of the overlapping flange 15 is prevented from extending beyond the shielding surface 21 in the y2 direction by the shielding surface 21. Therefore, the gap l2 remains without the gasket 23.

[0052] According to Figure 4 As can be seen in the cross-sectional view, the connector cover 20 includes a fixing mechanism 24, by which the connector cover 20 is fixed to the base 11. In this example, the connector cover 20 is held to the base 11 by screws 39, for example, held to the base 25 of the base 11.

[0053] The base 25 is immovably fixed to the shaft mechanism 16 of the retaining member 32. The structure 26 of the arm rest 12 is slidably supported on the base 25 by a sliding bushing 27, so that the arm rest 12 pivots between a primary position and a secondary position relative to the base 25 with the structure 26. The housing 28 of the arm rest 12 moves together with the arm rest 12 relative to the base 25 and the connector cover 20 fixed to the base 25. The housing 28 has an opening 37, and its sidewalls form a gap 38 with the circumferential surface 36 of the connector cover 20.

[0054] When the gasket 23 rests against the shielding surface 21 of the immovable connector cover 20, the side 22 rotates relative to the connector cover 20. Due to the gap l2, the gasket is not subjected to wear caused by friction, and gives the user a higher quality impression.

[0055] The first region 29 of the arm rest 12, near the axis, can pivot about the longitudinal axis m relative to the free second region 31. Because the second region 31 is at a certain distance from the gasket 23, the radial extension of the connector cover 20 will not be large enough to extend into the second region 31.

[0056] according to Figure 7 The arm rest 12 is arranged in a secondary position, while the base 11 does not change its position relative to the arm rest 12. Figure 2 The location.
