Description

Technical Field

[0001] The present invention relates to the field of seats, and particularly to a chain-shaped masking component and a slide rail. Background Art

[0002] Chinese Patent Publication No. CN110509823A discloses a masking component having a zipper and flexible ribs. The ribs and the strip are made by an integral molding process. At the same time, the ribs, the strip, and the plate-shaped component are made of different materials respectively to improve the durability and endurance performance of the masking component. Since no fixing structure is provided between the masking component and the fixed guide rail, the masking component will move relative to the fixed guide rail during use, affecting the overall appearance quality.

[0003] Chinese Utility Model Publication No. CN217791727U discloses a zipper structure for preventing foreign objects on a seat slide rail. The zipper rack is connected to the lower rail or the dust-proof rubber cover by sewing an elastic cloth. Ribs are arranged on the sewn elastic cloth. The rib structure can quickly and conveniently fix the sewn elastic cloth to the lower rail or the dust-proof rubber cover, and at the same time keep the sewn elastic cloth always in a tensioned state. When the technical solution of clamping connection between the dust-proof rubber cover and the lower rail is adopted, the dust-proof rubber cover will cause relative displacement or expose a gap when stepped on by the occupant above, affecting the overall appearance quality. When the technical solution of directly locking the sewn elastic cloth on the lower rail through a sheet metal part is adopted, the sewn elastic cloth and the zipper rack are easily overstretched due to the influence of the lateral dimension of the lower rail, affecting the appearance quality; during maintenance operations, the lower sewn elastic cloth, the zipper rack and the sheet metal part need to be replaced together, increasing the after-sales cost. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the purpose of the present invention is to provide a chain-shaped masking component and a slide rail, and further optimize the structures of various components on the premise of ensuring the firm fixation of the masking component to the lower track.

[0041] It can be understood that although the terms "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of the concept of the present application.

[0042] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals represent the same or functionally identical elements.

[0043] Figure 1 The structure of the mask member is shown. The mask member 1 is mainly composed of a pair of mask covers 160 adjacent to each other on both sides, and the mask covers 160 are connected by a zipper tape 100. The mask member 1 is fixed to the upper part of the lower track 200 in a laterally adjustable and independently removable manner by means of fasteners; when the mask member 1 is damaged, it can be replaced without disassembling the upper track 300 and the lower track 200. The zipper tape 100 is composed of a pair of mirror-image opposed tooth tapes 120 and connecting tapes 130. Two adjacent connecting tapes 130 are specifically connected together by a pair of tooth tapes 120 meshing with each other between the teeth. The separation and combination of the teeth between the tooth tapes 120 enable the zipper tape 100 to switch between the open and closed states. A support tape 140 is provided on the side of the connecting tape 130 away from the tooth tape 120. The connecting tape 130 is usually made of a soft material to facilitate close engagement with the tooth tape 120. Therefore, the connecting tape 130 is supported and formed longitudinally by the support tape 140 to facilitate connection with other components.

[0044] Reference Figure 2 and Figure 3 In an embodiment, the support tape 140 is made of a soft material, and ribs 141 extending longitudinally along the support tape 140 are provided on the support tape 140. Through holes 142 are formed in the ribs 141. A support bar 150 made of a hard material is inserted into the through holes 142 as a support skeleton. Preferably, the support tape 140 and the connecting tape 130 are made of the same material, and the support bar 150 is made of steel wire or hard plastic strip.

[0045] In an embodiment not shown, the support tape 140 is made of a hard material, preferably nylon, hard plastic, glass fiber or a mixture thereof. The support tape 140 and the connecting tape 130 are fixed by sewing, hot melting or secondary injection molding. Since the support tape 140 is made of a material with higher strength, the ribs 141 are solid and do not require additional insertion of hard materials to achieve support.

[0046] Figures 4 to 6The connection structure between the zipper tape and the cover plate is shown. A groove portion 163 extending along the length direction thereof is formed in the cover plate 160. The groove portion 163 forms a semi-open structure through the opening 163a on the side. The rib portion 141 is inserted into the groove portion 163, and the support tape 140 passes through the opening 163a and remains connected to the rib portion 141. The cross-section of the rib portion 141 is set to be a special shape, and the cross-sectional shape of the groove portion 163 is similar to that of the rib portion 141, so that the rib portion 141 cannot be flipped after being inserted into the groove portion 163, realizing the connection between a pair of cover plates 163 through the zipper tape 100. Preferably, the special cross-section of the rib portion 141 is an arc shape or a triangle, etc., so that it can be engaged in the groove portion 163 and is difficult to escape, which is a polygonal shape.

[0047] Figures 7 to 10 The matching schematic of the slider and the upper track is shown. The zipper tape 100 also has a pair of sliders 110 provided on the tape 120. One side of the slider 110 has a pulling and closing portion 111 for separating and combining the teeth of the adjacent pair of tapes 120, and the other side has a connecting portion 112 for fixing to the upper track 300. The connecting portion 112 is longitudinally provided with a receiving groove 113 for inserting into the upper track connecting bracket 310, and is locked to the upper track connecting bracket 310 through the mounting hole 114 provided on the side of the connecting portion 112 and the fastener 114. After being fixed, the slider 110 can rotate upward or downward, so that the pulling and closing portion 111 has a certain degree of freedom when separating and combining the teeth. Specifically, a pair of sliders 110 are respectively fixed at the end positions 311 on both sides of the upper track connecting bracket 310 through the connecting portion 112. The slider 110 is driven by the upper track 300 to move to realize the separation and combination of the teeth of the zipper tape 100, so that the zipper tape 100 always has an opening portion 4 for the upper track connecting bracket 310 to pass through, while the rest remains closed. Since the structure of the slider 110 is simple and it is fixed to the upper track connecting bracket 310 in a convenient manner, it can be adapted to various different types of upper tracks (such as C-shaped track, T-shaped track, W-shaped track, etc.).

[0048] Figures 11 to 13The schematic illustration of the fixing of the masking component and the lower rail is shown. At both ends of the masking cover 160, protruding connecting parts 161 are provided. A waist-shaped fixing hole 162 is formed in the connecting part 161. A pair of masking covers 160 are correspondingly fixed to the upper end surface 202 on one side of the lower rail 200 through a pair of front and rear fixing holes 162 by fasteners (a pair of upper end surfaces 202 correspond to a pair of masking covers 160). The fixing holes 162 at the front and rear ends of the masking cover 160 form fixing points with different longitudinal positions. The cooperation with the waist-shaped fixing holes 162 enables the masking cover 160 to finely adjust its lateral position during the fixing process so as to better match the vehicle interior trim. The zipper tape 100 located between the pair of masking covers 160 shields the upper port of the lower rail 200 to prevent foreign objects from falling in. After the masking component 1 is fixed, the remaining zipper tape 100 at both ends is received into the inner cavity 201 in the middle of the lower rail 200.

[0049] Figure 14 A further implementation manner of the dust-proof slide rail is shown. A rail end cover 300 is provided at the end 230 of the lower rail to shield the upper port. The rail end cover 300 absorbs the longitudinal tolerance of the covering component 1 and improves the matching quality.
