Abstract
Description
[Technical Field]
[0001] The present invention relates to a webbing for an occupant restraint belt and a seat belt device. [Background technology]
[0002] Long occupant restraint belts (seat belts) that restrain occupants in vehicles are required to include information and markings stipulated by the laws and regulations of each country. Conventionally, labels with the necessary information printed on them have been sewn onto the webbing (see, for example, Patent Document 1). However, this required separate label preparation and a sewing process, which increased costs. In addition, webbing with sewn labels did not look attractive. Furthermore, the location where the label could be sewn onto the webbing was limited due to considerations such as seat belt retraction.
[0003] Instead of sewing on a label, a method of laser engraving the necessary information on the tongue plate is also known, but the engraving space on the tongue plate is narrow, making it difficult to engrave all the necessary information. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-238521 Summary of the Invention [Problem to be solved by the invention]
[0005] An object of the present invention is to provide a webbing for an occupant restraint belt and a seat belt device on which desired information can be written without using a label. [Means for solving the problem]
[0006] The webbing for an occupant restraint belt of the present invention is a webbing for an occupant restraint belt that constitutes a long occupant restraint belt for restraining a vehicle occupant, and has predetermined information transferred and printed on its surface.
[0007] The seat belt device of the present invention comprises a seat belt constructed using the webbing for an occupant restraint belt of the present invention, a retractor that winds up the seat belt, a buckle fixed to the vehicle, and a tongue that is provided on the seat belt and engages with the buckle. [Effects of the Invention]
[0008] According to the present invention, desired information can be written on the webbing for the occupant restraint belt without using a label. [Brief explanation of the drawings]
[0009] [Figure 1] 1 is a perspective view of a seat belt device according to an embodiment. [Figure 2] FIG. 2 is a plan view of the seat belt according to the embodiment. DETAILED DESCRIPTION OF THE INVENTION
[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0011] As shown in Fig. 1, a seat belt device 1 is provided in a vehicle seat 2 of an automobile or the like. The vehicle seat 2 has a seat cushion 2b on which an occupant sits and a seat back 2a that rises from the rear of the seat cushion 2b. The vehicle seat 2 is a seat that can accommodate one occupant, such as a driver's seat, a passenger seat, or a captain's chair in the rear. The vehicle seat 2 may also be a bench seat that can accommodate multiple occupants, with seat belt devices installed for each occupant.
[0012] A typical seat belt device 1 is a three-point seat belt device, which includes a seat belt retractor 3 (hereinafter referred to as "retractor 3") arranged on or near a vehicle seat 2, a seat belt 4 made of webbing that is retractably wound around the retractor 3 and restrains the occupant in an emergency, a guide anchor 5a (shoulder anchor) that guides the seat belt 4 retracted from the retractor 3 toward the occupant's shoulder, a tongue 6 that is slidably supported on the seat belt 4 guided from the guide anchor 5a, and a buckle 7 into which the tongue 6 is releasably inserted and engaged.
[0013] The buckle 7 is connected to the seat frame by a connecting member such as a webbing.
[0014] The seat belt 4 includes a shoulder belt 4a that restrains the occupant's shoulders, chest, etc., and a lap belt 4b that restrains the occupant's waist, etc. The seat belt 4 is divided into the shoulder belt 4a and the lap belt 4b by a tongue 6.
[0015] The retractor 3 is a winding device that enables winding and unwinding of the seat belt 4, and when acceleration equal to or greater than a predetermined value is detected in an emergency, etc., it restricts the seat belt 4 from being unwound from the retractor 3. The retractor 3 is also provided with a load limiter mechanism (not shown) that keeps the restraining force of the seat belt 4 applied to the occupant at a constant level.
[0016] The leading end of the seat belt 4 in the withdrawal direction after being withdrawn from the retractor 3 is inserted through the opening of the anchor 5b and connected to the anchor 5b by being folded back and sewn. The anchor 5b is fixed to the seat frame or the vehicle body on the opposite side of the vehicle seat 2 from the buckle 7.
[0017] The webbing of the seat belt 4 is formed by weaving a plurality of warp and weft threads so that they extend perpendicular to each other. The threads used for the webbing are preferably multifilament threads made by twisting and converging polyester fibers or nylon fibers. The width of the webbing is not particularly limited, but is, for example, about 50 mm.
[0018] As shown in FIG. 2, the webbing of the seat belt 4 displays information 8 about various items, such as the name of the manufacturer of the seat belt 4, the model name and manufacturer name of the vehicle in which the seat belt device 1 is installed, marks and wording required by the laws and regulations of the country in which it is sold, and a two-dimensional code.
[0019] In this embodiment, the information 8 is transfer-printed onto the surface of the webbing. The transfer method is not particularly limited, but for example, ink is applied to a PET film to form letters or the like, adhesive glue is applied on the letters to prepare a transfer sheet, the transfer sheet is superimposed on the webbing, and heat and pressure are applied using a heat press machine, thereby transferring and printing the information 8 onto the webbing.
[0020] Alternatively, the information 8 may be transferred and printed by pouring ink onto a plate with a recessed portion where the information to be printed will be printed, transferring the ink on the plate to an elastic silicone pad as a primary transfer, and then pressing the silicone pad against the webbing as a secondary transfer.
[0021] In this embodiment, since a label is not used, a sewing process is not required, and there is a high degree of freedom in the printing position, resulting in a good appearance. Furthermore, compared to methods using labels or methods of engraving on the tongue plate, it is possible to print over a wider area, so more information can be written. Furthermore, since it is transfer printing, it is possible to express fine patterns such as two-dimensional codes.
[0022] The printing position of the information 8 (first information) is arbitrary, but for example, it is printed on the leading end of the seat belt 4 in the withdrawal direction (near the anchor 5b of the lap belt 4b).
[0023] Also, second information different from the first information at the leading end may be transferred and printed at the rear end in the withdrawal direction of the seat belt 4, for example, at a position that becomes visible when the seat belt 4 is withdrawn to its maximum extent from the retractor 3. For example, the second information is a statement or mark indicating that the seat belt 4 is a genuine product.
[0024] According to this embodiment, the additional information can be transferred and printed onto the seat belt 4 even after the seat belt device 1 has been installed in the vehicle.
[0025] Cautions may be transferred and printed onto the belts of child car seats.
[0026] The present invention is not limited to the above-described embodiments, and the components can be modified and embodied in practice without departing from the spirit of the invention. Furthermore, various inventions can be formed by appropriately combining multiple components disclosed in the above-described embodiments. For example, some components may be omitted from all the components shown in the embodiments. Furthermore, components from different embodiments may be appropriately combined.
