Description

Technical Field

[0001] This disclosure relates to the field of automotive safety technology, and more specifically to a seat belt system and a seat system. Background Technology

[0002] Seat belt systems typically include seat belts and pretensioners. The pretensioner's function is to quickly tighten the webbing after a collision, eliminating the gap between the occupant and the webbing. This prevents the occupant from lurching forward and reduces the injury they suffer in a collision.

[0003] Existing pretensioners can be installed in the seat post. In addition to the pretensioner, the seat belt system also includes a tube (such as a steel tube) and a steel cable. The steel tube is fixed inside the seat post (also known as the seat tube). The pretensioner is located inside the steel tube and can move axially inside the steel tube. One end of the steel cable is fixedly connected to the pretensioner and the other end is fixedly connected to the webbing. When a car collides, the pretensioner will be triggered and move axially inside the steel tube, and pull the webbing in the post toward the steel tube through the steel cable, thereby tightening the webbing.

[0004] In existing technologies, seatbelt systems also include seatbelt guides, but these guides are fitted at one end onto the tube column and at the other end fixed to the seat cushion panel. When the seat cushion panel rotates with the seat, it causes the seatbelt guide to rotate around the tube column. At this time, the tube column is stationary relative to the seat cushion panel, and the end of the seatbelt guide that contacts the tube column rotates relative to the seatbelt guide, resulting in friction between the seatbelt guide and the tube column, thus generating noise. This is perceived as an "abnormal noise" by occupants, causing discomfort and potentially leading to complaints. Utility Model Content

[0005] The purpose of this disclosure is to provide a seat belt system that avoids noise generated by the seat belt guide and column during seat use.

[0006] Therefore, one aspect of this disclosure relates to a seat belt system for installation in a seat, the seat belt system having: a seat belt with webbing and a pretensioning assembly cooperating with said seat belt, wherein the seat has a column for receiving the pretensioning assembly, characterized in that the seat belt system further includes a seat belt guide having an opening for the webbing to pass through, the seat belt guide being able to be arranged and connected such that no relative friction occurs between the seat belt guide and the column.

[0007] In this disclosure, the seatbelt guide can be arranged and connected in such a way that no relative friction occurs between the seatbelt guide and the column. This advantageous arrangement and connection of the seatbelt guide effectively prevents friction between the seatbelt guide and the column, thereby avoiding annoying noise. This prevents unpleasant rattles and groans inside the vehicle. Furthermore, it also prevents wear caused by friction between the seatbelt guide and the column.

[0008] In some embodiments, the seatbelt guide can be arranged and connected so as not to move relative to the tube column. Thus, whether the seat cushion side can rotate around the tube column or not, the seatbelt guide will not move relative to the tube column, thereby eliminating noise.

[0009] In some embodiments, the seatbelt guide is configured to be directly fixed to the tube column without being connected to the seat cushion side. Thus, the seatbelt guide can be fixed directly to the tube column independently of, or "decoupled" from, the seat cushion side, so that movement of the seat cushion side will not cause friction between the seatbelt guide and the tube column.

[0010] In some embodiments, the seatbelt guide is configured to be inserted into and fixedly connected to the wall of the tubing column. This allows for a secure fixation of the seatbelt guide to the tubing column wall.

[0011] In some embodiments, the seatbelt guide is configured for secure attachment to the column via a threaded connection. This allows for a secure yet detachable connection of the seatbelt guide to the column.

[0012] In some embodiments, the seatbelt guide is configured to be fixedly connected to a column bracket without being connected to the seat cushion side, wherein the column bracket for supporting the column is fixed to the column. Thus, the seatbelt guide can also be fixedly connected to the column bracket fixed to the column independently of, or "decoupled from," the seat cushion side, so that movement of the seat cushion side will not cause friction between the seatbelt guide and the column.

[0013] In some embodiments, the seatbelt guide is configured to insert one end into the wall of the column and the other end is fixedly connected to a column support. This allows for advantageous connection and fixation of the seatbelt guide at both the column wall and the column support.

[0014] In some embodiments, the seatbelt guide is configured for secure attachment to the column support via a threaded connection. This allows for a secure yet detachable connection of the seatbelt guide to the column support.

[0015] In some embodiments, the seatbelt guide can be arranged and connected in a manner that prevents it from contacting the tubular column. This ensures that the seatbelt guide is "decoupled" from the tubular column, in which case no friction will occur between the seatbelt guide and the tubular column under any circumstances.

[0016] In some embodiments, the seatbelt guide is configured to be spaced apart from the tubing along the axial direction of the tubing. This spaced-apart arrangement of the seatbelt guide from the tubing ensures that no friction occurs between the seatbelt guide and the tubing.

[0017] In some embodiments, the seatbelt guide is configured to be at least partially secured to the seat cushion side when the seat cushion side cannot rotate relative to the tube column. Because the seat cushion side is arranged to be non-rotatable relative to the tube column, the seatbelt guide can still be partially secured to the seat cushion side, and no friction occurs between the seatbelt guide and the tube column during seat use.

[0018] In some embodiments, the seatbelt guide is configured to insert one end into the wall of the tube column and the other end is fixedly connected to the side of the seat cushion. Similarly, because the side of the seat cushion is arranged to be non-rotatable relative to the tube column, no friction will occur between the seatbelt guide and the tube column during seat use, even though the other end of the seatbelt guide is fixedly connected to the side of the seat cushion.

[0019] In some implementations, the opening of the seat belt guide can be coaxially arranged with the opening of the column.

[0020] In some implementations, the seatbelt guide is configured to guide the seatbelt webbing into the column when the pretensioning assembly is triggered and / or to guide the webbing to avoid contact between the webbing and the sharp metal edge of the seat.

[0021] Another aspect of this disclosure relates to a seating system, characterized in that the seating system includes a seat belt system and a seat according to one of the foregoing embodiments, the seat belt system being installed in the seat, wherein the seat includes a column for receiving a pretensioning assembly and a seat cushion with cushion sides.

[0022] In some embodiments, the side portion of the cushion is configured as a cushion wall panel.

[0023] The technical features mentioned above, those to be mentioned below, and those shown individually in the accompanying drawings can be combined arbitrarily, provided that the combined technical features are not contradictory. All feasible combinations of features are the technical content explicitly described herein. Any one of the multiple sub-features contained in the same statement can be applied independently, without necessarily being applied together with other sub-features. Attached Figure Description

[0034] First, let's use... Figures 1 to 4This description describes a first embodiment of a seatbelt system according to the present disclosure. The seatbelt system is for installation in a seat 100 having a seat cushion with a cushion side 120. In the first embodiment, the seatbelt system includes a seatbelt with webbing 500 and a pretensioning assembly 400 cooperating with the seatbelt. The seat 100 has a column 110 configured to receive the pretensioning assembly 400. Furthermore, the seatbelt system includes a seatbelt guide 900 having an opening through which the webbing 500 passes. The opening of the seatbelt guide 900 and the opening of the column 110 are coaxially arranged. The seatbelt guide 900 is configured to guide the webbing 500 of the seatbelt into the column 110 when the pretensioning assembly 400 is triggered. Additionally or alternatively, the seatbelt guide 900 is configured to guide the webbing 500 to avoid contact between the webbing 500 and the sharp metal edges of the seat 100. To support the tubular column 110, the safety belt system also includes a tubular column bracket 130 for supporting the tubular column 110, the tubular column bracket 130 being fixed, and particularly welded, to the tubular column 110. For example... Figure 1 and Figure 2 As shown, the seat cushion of seat 100 can switch between an initial position and a rotated position. Figure 1 Rotate from the initial position to Figure 2 During the rotation process, the seat cushion side 120 rotates around the central longitudinal axis of the tube post 110 (also known as the seat post). If, as in a conventional design, the seat belt guide 900 is inserted into the tube wall of the tube post 110 at one end and fixed to the seat cushion side 120 at the other end, the portion of the seat belt guide 900 inserted into the tube post 110 will rotate around the tube post 110 due to the rotation of the seat cushion side 120, thereby causing relative friction with the tube post 110 and generating noise. In the first embodiment, to avoid noise, the seat belt guide 900 is arranged and connected such that there is no relative friction between the seat belt guide 900 and the tube post 110, wherein the seat belt guide 900 is arranged and connected in a way that prevents relative movement with the tube post 110, such as... Figure 4 As shown, the seatbelt guide 900 is fixedly connected to the column support 130 without being connected to the seat cushion side 120. Specifically, the seatbelt guide 900 has one end inserted into the wall of the column 110, and the other end is fixedly connected, preferably by a threaded connector 910 (such as a screw), to the column support 130. In the first embodiment, by "decoupling" the seatbelt guide 900 from the seat cushion side 120, movement of the seat cushion side 120 does not cause movement of the seatbelt guide 900, thereby ensuring no relative friction occurs between the seatbelt guide 900 and the column 110, thus avoiding noise generation.

[0035] Then, with the help of Figure 5 and Figure 6 A second embodiment of the seatbelt system according to this disclosure is described. The main difference between the second embodiment and the first embodiment lies in the arrangement and connection form of the seatbelt guide 900. For example... Figure 5 and Figure 6 As shown, in the second embodiment, the seatbelt guide 900 is directly and preferably directly and fixedly connected to the column 110 without being connected to the seat cushion side 120, preferably by means of a threaded connector 910 (such as a screw). Other aspects can be referred to the previous description of the first embodiment. Here, as from... Figure 6 As can be clearly seen, the seat belt guide 900 is inserted into and fixedly connected to the wall of the column 110, preferably by a threaded connector 910 (such as a screw). In the second embodiment, by directly fixing the seat belt guide 900 to the column 110 without connecting it to the seat cushion side 120, the seat belt guide 900 is also "decoupled" from the seat cushion side 120. This ensures that movement of the seat cushion side 120 does not cause movement of the seat belt guide 900, thereby ensuring that there is no relative friction between the seat belt guide 900 and the column 110, thus avoiding noise.

[0036] The following uses Figure 7 and Figure 8 A third embodiment of the seatbelt system according to this disclosure is described. In the third embodiment, the seatbelt guide 900 is arranged and connected so as not to contact the column 110. Reference can be made substantially to the description of the first embodiment in other respects. In the third embodiment, the seatbelt guide 900 is arranged spaced apart from the column 110 along the axial direction of the column 110. For this purpose, at least a portion of the seat cushion side 120 is arranged spaced apart from the column 110 along the axial direction of the column 110, and the seatbelt guide 900 is integrally fixed to the seat cushion side 120. Besides the arrangement shown in the third embodiment, other methods are conceivable to ensure that the seatbelt guide 900 is arranged and connected so as not to contact the column 110. For example, the seatbelt guide 900 may be fixed to another support member that is not connected to or does not contact the column 110. In the design scheme in which the seat belt guide 900 is arranged and connected without contacting the tube column 110, the seat belt guide 900 is "decoupled" from the tube column 110. Therefore, even if the movement of the seat cushion side 120 causes the seat belt guide 900 to move, it will not cause relative friction between the seat belt guide 900 and the tube column 110, thereby ensuring that noise is avoided during the use of the seat 100.

[0037] Finally, with the help of Figure 9A fourth embodiment of the seatbelt system according to this disclosure is described. In this fourth embodiment, the seat cushion of the seat 100 does not rotate relative to the tube post 110, that is, the seat cushion side 120 is arranged so as not to rotate relative to the tube post 110. In this case, it is conceivable to at least partially fix the seatbelt guide 900 to the seat cushion side 120. Figure 9 As shown, the seat belt guide 900 can be inserted into the wall of the tube column 110 at one end and fixedly connected to the side portion 120 of the seat cushion at the other end. Since the seat cushion of the seat 100 does not rotate relative to the tube column 110, relative friction will never occur when the seat belt guide 900 and the tube column 110 are in contact, thereby ensuring that noise is avoided during the use of the seat 100.
