Description
Technical Field
The present invention relates to a safety device for a vehicle, and in particular to a seatbelt assembly.
Background
A seatbelt assembly for a vehicle is a safety device for restraining an occupant at the time of a collision, and preventing the occupant from having a secondary collision with a steering wheel, an instrument panel, or the like at the time of the collision, or from being rushed out of the vehicle to cause a death injury at the time of the collision.
The seatbelt assembly includes a seatbelt and a guide fixed to the vehicle and having a window portion where the seatbelt can change direction and move freely. Since the belt is able to move relative to the guide, the friction caused by this movement will most likely cause the coating on the guide to fall off. The coating of the guide member is stripped off which affects the force to which the shoulder of the passenger is subjected, which adversely affects the performance of the seat belt assembly.
Accordingly, a harness assembly having a long service life and high reliability is desired.

According to an embodiment of the invention, the coating is applied to the guide using a jet-combined heating process or by flame spraying.
Drawings
Features, advantages and technical effects of exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the drawings, like numbering represents like elements, and wherein:
fig. 1 illustrates a harness assembly according to an embodiment of the present invention.
Figure 2 illustrates a portion of the components of a harness assembly according to an embodiment of the present invention.
Detailed Description
A specific embodiment of the harness assembly according to the present invention will be described below with reference to the accompanying drawings. The following detailed description and drawings are included to illustrate the principles of the invention, which is not limited to the preferred embodiments described, but rather are intended to cover various embodiments of the invention, alone or in any combination, and the scope of the invention is defined by the claims.
In addition, spatially relative terms (such as "upper," "lower," "left," and "right," etc.) are used to describe one element's relative positional relationship with another element as illustrated in the figures. Spatially relative terms may therefore apply in other orientations than those illustrated in the figures, when used. It will be apparent that although for ease of illustration all of these spatially relative terms refer to the orientation shown in the drawings, those skilled in the art will appreciate that orientations other than those shown in the drawings may be used.
Fig. 1 illustrates a harness assembly according to an embodiment of the present invention. Figure 2 illustrates a portion of the components of a harness assembly according to an embodiment of the present invention. A harness assembly according to an embodiment of the invention is described below with reference to fig. 1 and 2.
As shown in fig. 1, a harness assembly 10 according to an embodiment of the present invention is used in a vehicle 20. The seatbelt assembly 10 includes a seatbelt 100 for restraining an occupant in the vehicle 20 and a guide 200, the guide 200 being fixed to the vehicle 20 (typically at the B-pillar) and having a window portion 200A. As clearly shown in fig. 1, the seat belt 100 passes through the window portion 200A and is able to change direction at the window portion 200A, in other words, the seat belt 100 extends in a first direction to the window portion 200A and changes direction at the window portion 200A to extend in a second direction, which can be seen to be substantially opposite. In the orientation of the safety assembly 10 shown in fig. 1, the first direction and the second direction may be understood as the up-down direction, i.e., the webbing 100 extends downward on the right side of the guide 200 after extending upward from the left side of the guide 200 through the window portion 200A, or the webbing 100 extends downward on the left side of the guide 200 after extending upward from the right side of the guide 200 through the window portion 200A. And, the seat belt 100 can be freely moved at the window portion 200A to change the length of the seat belt worn by the passenger, i.e., to adjust the degree to which the seat belt is tightened against the passenger. The guide 200 in the seatbelt assembly 10 according to the embodiment of the present invention is described in detail below.
As shown in fig. 2, the guide member 200 includes a center member 201, side covers 202, and a connection member 203 for connecting the center member 201 and the side covers 202 together, as an example, and a specific connection manner will not be described in detail herein, and it will be understood by those skilled in the art that the existing connection manner is suitable for use herein. Also, the above-mentioned window portion 200A is provided at the centerpiece 201. In addition, the center member 201 is also provided with a mounting hole through which a fastener (e.g., a bolt) is passed to fix the guide member 200 to the vehicle 20, and the guide member 200, which is usually fixed to the vehicle 20, is located at a position above the shoulder of the passenger (e.g., at the B-pillar).
In the harness assembly of the present invention, the guide comprises a coating formed from a synthetic material comprising a fluorine-containing matrix material and a low friction hard material. For example, preferably, in the example shown in fig. 2, the coating may be provided on all the surfaces of the centerpiece 201 described in the above embodiment.
Therefore, in the harness assembly of the present invention, the guide includes a coating layer formed of a synthetic material including a fluorine-containing base material and a low-friction hard material, thereby exhibiting superior high temperature resistance and superior hardness due to a higher degree of polymerization of the fluorine-containing base material itself; in addition, the addition of low-friction hard materials can further increase the melting point of the synthetic material. Therefore, when the coating of the guide member is repeatedly rubbed by the seat belt for many times, the material forming the coating has characteristics of low friction and hardness so that the coating is wear-resistant and has a high melting point, and thus the coating is not easily peeled off by the friction of the seat belt. Therefore, the safety belt component has the characteristics of long service life and high reliability.
Optionally, the low friction hard material comprises at least one of a molybdenum containing compound, a silicon containing compound, graphite. This is merely an example, however, and low friction hard materials also include alumina, carbon powder, for example. It will be appreciated that this gives the synthetic material the function of self-lubrication.
Optionally, the low friction hard material comprises, in weight percent, 8-12% of the molybdenum containing compound, or 1-5% of the silicon containing compound, or 8-12% of the graphite.
Optionally, the molybdenum-containing compound is molybdenum disulfide; and, optionally, the silicon-containing compound is silicon dioxide.
Optionally, the thickness of the coating is set to 15-100 microns.
Optionally, the portion of the guide having the coating is configured to have a non-uniform surface configuration to prevent contact with the full surface of the belt.
Optionally, the coating is applied to the guide after the guide is grit blasted and shot peened.
Optionally, the coating is applied to the guide using a spray-on-heat process, or by flame spraying. It will be appreciated that the two above solutions apply to the liquid fluorine-containing matrix material and the solid fluorine-containing matrix material, respectively.
Optionally, the surface of the guide to be provided with the coating has a roughness Ra <2 microns.
As described above, although the exemplary embodiments of the present invention have been described in the description with reference to the drawings, the present invention is not limited to the above-described embodiments, and the scope of the present invention should be defined by the claims and their equivalents.
