[Figure 11] This is a plan view of a belt assembly according to a sixth embodiment of the present invention. [Modes for carrying out the invention]

[0059] Exemplary embodiments will be described in more detail with reference to the attached drawings. In the drawings, the same reference numeral may refer to the same or functionally identical components. When describing an embodiment with reference to one of the drawings, other drawings may be referenced. If a component and / or reference numeral mentioned in the description of a drawing does not appear in that drawing, the same or functionally identical component and / or corresponding reference numeral in another drawing may be referenced.

[0060] First, referring to Figures 2 to 6, a vehicle belt assembly 2 according to a first embodiment of the present invention and a steering wheel 6 according to one embodiment of the present invention are described. The steering wheel is an exemplary vehicle mechanism for a vehicle, including the belt assembly 2. The vehicle (not shown) may be an automobile, in particular a passenger car.

[0061] The belt assembly 2 includes a flexible belt body 20, which extends linearly, has a substantially constant width, and has two opposite ends. The belt body 20 is provided with attachments 21, 23 fixed to each of the two ends. The attachments 21, 23 are integrally connected to each end of the belt body 20 in the form of overmolded parts by a plastic injection molding process, thus forming the first mounting end 22 and the second mounting end 24 of the belt assembly 2. The second mounting end 24 has a mounting hole 25. The mounting hole 25 may be formed as an oval through hole, and the major axis of the oval through hole may extend substantially parallel to the longitudinal direction of the belt body 20. In some embodiments, the same or similar material as that used for vehicle safety belts may be used as the material for the belt body 20. In some embodiments, the material for the belt body 20 may be substantially inelastic or may have a predetermined elasticity.

[0062] Details of the structure of the two mounting ends 22 and 24 of the belt assembly 2 can be seen in Figures 4 and 5. Figure 4 is a longitudinal partial cross-sectional view along the longitudinal centerline of the belt assembly 2 in the area of ​​the first mounting end 22 of the belt assembly 2 when the belt assembly 2 is used exemplary with the steering wheel 6, and Figure 5 is a longitudinal partial cross-sectional view along the longitudinal centerline of the belt assembly 2 in the area of ​​the second mounting end 24 of the belt assembly 2 when the belt assembly 2 is used exemplary with the steering wheel 6.

[0063] As shown in Figure 4, at the first mounting end 22 of the belt assembly 2, the first attachment 21 in the form of an overmolded part can form a step at the first end of the belt body 20 relative to each of the two sides of the belt body 20. Similarly, as shown in Figure 5, at the second mounting end 24 of the belt assembly 2, the second attachment 23 in the form of an overmolded part can form a step at the second end of the belt body 20 opposite to the first end, relative to each of the two sides of the belt body 20. It can be seen that the step at the second mounting end 24 is optional. In embodiments not shown, the second mounting end 24 may not have a step.

[0064] In a modified example not shown, instead of an overmolded part, the first attachment 21 is integrally connected to the belt body 20 at the first end of the belt body 20 in the form of an injection-molded part (lateral injection-molded part) on only one side surface of the belt body 20. Therefore, according to this modified example, the first mounting end 22 of the belt assembly 2 has only one step on only one side surface of the belt body 20 (either the first side surface 26 or the second side surface 27).

[0065] In the embodiment shown in Figure 2, the first mounting end 22 and the second mounting end 24 have different external shapes. In a modified example not shown, the first mounting end may be modified to have the same external shape as the second mounting end 24 shown in Figure 2. Similar to the first mounting end 22 in Figure 2, the modified first mounting end does not have a mounting hole.

[0066] In another modified example not shown, the belt body 20 may have a first attachment 21 at its first end, as shown in Figure 2, and therefore the belt assembly has a first mounting end. The belt body 20 does not need to have a second attachment 23 at its second end, as shown in Figure 2, and therefore the belt assembly does not have a second mounting end. In this case, the second end of the belt body 20 may be configured as a free end and may have decorative parts, such as decorative parts made of fabric.

[0067] Figure 3 is a perspective view of a vehicle mechanism including a belt assembly 2 according to one embodiment of the present invention, which provides a steering wheel 6 for a vehicle, the belt assembly 2 forming a decorative member of the steering wheel 6. The steering wheel 6 has a rim 61 and a central hub 62, which are connected by two spokes 63, the spokes 63 may be provided with various operating elements. A structural unit (not shown) may be mounted on the central hub 62, the structural unit may include a driver airbag and a horn activation device for the vehicle horn.

[0068] As shown in Figures 3 and 4, the belt assembly 2 may be detachably mounted to the rim 61 of the steering wheel 6 using its first mounting end 22. For this purpose, the rim 61 of the steering wheel 6 may be provided with a first receiving member 3. The first receiving member 3 may be an integral part of the rim 61's frame, an injection-molded part on the frame, or a separate component mounted to the rim 61. The first receiving member 3 may have a receiving groove 30 and a projection extending from the groove wall of the receiving groove 30, the projection of which may form a first fastener 31. The belt assembly 2 can be inserted into the receiving groove 30 of the first receiving member 3 using its first mounting end 22. The first fastener 31 can cooperate with the first step 221 of the first mounting end 22, which is located on the first side surface 26 of the belt body 20. After the belt assembly 2 is inserted into the receiving groove 30 of the first receiving member 3 using its first mounting end 22, a blocking member 4 can be inserted into the receiving groove 30. The blocking member 4 can hold the position of the first mounting end 22 of the belt assembly 2 within the receiving groove 30 so that the first mounting end 22 cannot move within the receiving groove 30 in a direction perpendicular to the direction in which the first mounting end 22 is pulled out of the receiving groove 30. The blocking member 4 may have a second fastener 41, which may cooperate with a second step 222 of the first mounting end 22 located on the second side surface 27 of the belt body 20 opposite the first side surface 26. The second fastener 41 may be configured as a step of the blocking member 4. The first mounting end 22 cannot be pulled out of the receiving groove 30 by the cooperation of the two fasteners 31, 41 and the two steps 221, 222 of the first mounting end 22, and therefore can be securely held in the receiving groove 30. The blocking member 4 may be held to the rim 61 of the steering wheel 6 by any suitable method. For example, the blocking member 4 may be held to the rim 61 in a separable manner by screw connections or snap-fit ​​connections. If it is necessary to replace the belt assembly 2, the blocking member 4 may be separated from the rim 61, and then the first mounting end 22 may be removed from the receiving groove 30.

[0069] As shown in Figures 3 and 5, the belt assembly 2 can be detachably mounted to the hub 62 at the center of the steering wheel 6 using its second mounting end 24. For this purpose, the hub 62 may be provided with a second receiving member 5. Figure 5 shows the connection structure of the second mounting end 24 of the belt assembly 2 at the hub 62 at the center of the steering wheel 6. Figure 6 is a perspective view of an exemplary second receiving member 5.

[0070] The second receiving member 5 may have a plate-like portion 51 having a first side and a second side on opposite sides, the plate-like portion 51 having a mounting surface 54 on its first side. The receiving hole 55 penetrates the plate-like portion 51 and extends into a cylindrical portion 56 protruding from the second side of the plate-like portion 51. When the second mounting end 24 is attached to the second receiving member 5 by a screw bolt 7, the receiving hole 55 may be a screw hole, and the screw bolt 7 is screwed into the receiving hole 55 through the mounting hole 25 of the second mounting end 24.

[0071] The second receiving member 5 may have a guide portion 52 that is bent from the plate-like portion 51 toward its first side surface, and the guide portion 52 is configured to guide the belt body 20 in a taut state. The guide portion 52 may have a guide groove 50, which may have a laterally extending guide edge 58 and two guide legs 57 extending from the guide edge 58. The guide edge 58 is configured to guide the upper first side surface 26 of the belt body 20 in a taut state so that the first side surface 26 of the belt body 20 can slide along the guide edge 58. Each guide leg 57 is configured to guide one of the two longitudinal edges 28 of the belt body 20 in a taut state. The visible portion of the belt body 20 can maintain its position and orientation by the guide portion 52 that guides the belt body 20.

[0072] When the belt body 20 is taut, the second mounting end 24 of the belt assembly 2 can seat on the flat mounting surface 54 of the plate-like portion 51 using the edge of its end. The flat side of the second mounting end 24 facing the second receiving member 5 may form an inner angle with the mounting surface 54. The inner angle can be changed to adjust the tension of the belt body 20 by operating the screw bolt 7. For example, if the performance of the belt assembly 2 deteriorates during use and therefore becomes slack, the screw bolt 7 can be properly screwed into the receiving hole 55, thereby maintaining the belt body 20 at a predetermined tension. In this case, the inner angle decreases accordingly. The screw bolt 7 may be lockable. Alternatively or additionally, the screw bolt 7 may be equipped with a means to prevent loosening.

[0073] The second receiving member 5 may have a mounting portion 53 that is bent from the plate-like portion 51 toward its second side surface, and the mounting portion 53 is configured to mount the second receiving member 5 to the hub 62 at the center of the steering wheel 6. For this purpose, the mounting portion 53 may have a plurality of mounting holes and may be securely fixed to the hub 62 by a plurality of fasteners.

The first attachment component 71, the first end of the belt body 20a, and the second attachment component 72 form a sandwich structure and are fixed and connected to each other. For this purpose, the first attachment component 71 and the second attachment component 72 may be fixed to each other by a fastener 75. The second attachment component 72 may have a threaded sleeve 73, and the first attachment component 71 may have a recess 74 for receiving the threaded sleeve 73. The threaded sleeve 73 passes through the opening 76 of the belt body 20a and is inserted into the recess 74. In the embodiment shown in Figure 7, the fastener 75 is a threaded bolt that is screwed from the first attachment component 71 into the threaded sleeve 73. Additionally, in the production process of the belt assembly 2a, before the first end of the belt body 20a is seated on the second attachment part 72, an adhesive may be applied to the first end of the belt body 20a, and the cured adhesive may form an adhesive layer 70 to bond the belt body 20a and the second attachment part 72. The fixed connection between the first attachment 21a and the first end of the belt body 20a may be achieved by one or more fasteners 75. For example, in the width direction of the belt body 20a, one fastener 75 may be positioned in the center of the first mounting end 22a, or two fasteners 75 may be positioned side by side.

[0075] The belt assembly 2a may have a second mounting end (not shown) on the opposite side of the first mounting end 22a.
