In general, car seats are produced through subcontractors, so the produced car seats are transported to finished car manufacturers and installed on vehicles.

Therefore, for pallets for transporting car seats produced by partner companies to finished car companies, Korean Patent Publication No. 10-2018-0124575 'Lightweight Pallet' and Registered Patent No. 10-2041856 'Pallet for Car Seat Transport' have already been provided. have.

That is, in the case of 'Lightweight Pallet' in Patent Publication No. 10-2018-0124575, a lightweight volume reinforcement made of metal foam or honeycomb, and an internal reinforcement block and an edge reinforcement block are combined between an aluminum upper plate and a lower plate having an adhesive pad on the inner surface. After bonding and fixing by heat pressing, it is configured to have strong strength while reducing the weight. Registration Patent No. 10-2041856 'Car seat transport pallet' connects and installs the first and second fixing bars to the base plate, but the base plate and the second fixing bar A rack ratchet tensioner is connected between the two parts, so that even if a gap occurs between the second fixing bar and the second fixing bar due to the movement of the upper car seat when the car seat is loaded and transported, the rack ratchet tensioner eliminates the gap and prevents the car seat from being separated. is configured to give

However, the above-mentioned car seat transport pallet can be said to be able to satisfy the intended purpose, but further strength cannot be expected, and when used for a long time, moisture or various foreign substances penetrate between the upper and lower plates and the bulk reinforcement material and the adhesive force of the adhesive pad is weakened. As these are separated and their service life is reached, problems such as increased cost burden due to repurchasing occur.

It is a view showing the support block of the jig for fixing the car seat.

1 to 3 , the vehicle seat fixing jig 10 according to an embodiment of the present invention includes a base plate 100 provided in a thin plate shape, and a connecting piece on the upper surface of the base plate 100 through A plurality of support blocks 300 fixed to the upper surface of the base plate 100 and supported by the first and second fixing bars 200 connected to and fixing the vehicle seat may be provided.

The base plate 100 includes an aluminum upper plate 110 and a lower plate 120 provided in a thin plate shape, and a pair of adhesive pads 130 respectively provided on the inner surfaces of the upper plate 110 and the lower plate 120 , and , The volume reinforcement 140 provided in the shape of any one of metal foam or honeycomb between the upper plate 110 and the lower plate 120, and the volume reinforcement material 140 by bonding to one surface of the volume reinforcement material 140 to reinforce the inside It may include an inner reinforcing block 150 made of aluminum, and a frame reinforcing block 160 made of aluminum provided on the edge of one surface of the volume reinforcing material 140 to reinforce the edge of the volume reinforcing material 140 .

It can be joined and fixed by thermal pressure.

And the base plate 100, the upper plate 110, the lower plate 120, the inner reinforcement block 150 and the edge reinforcement block 160, etc. are preferably made of a lightweight material such as aluminum, and the volume reinforcement 140 is lightweight It is made of metal foam or honeycomb to reduce the weight, and the internal reinforcement block 150 is inserted into the coupling hole 141 formed in the reinforcement portion of the volume reinforcement 140 to partially reinforce the strength, and the edge reinforcement block is a volume reinforcement ( 140) may be provided in the form of going around the side portion of the base plate 100 may be formed.

In addition, a primer layer is formed on the outer surface of the base plate 100 by applying a primer as a whole, and polyurea is spray coated on the primer layer and dried to form a polyurea layer as a whole on the outer surface of the base plate 100 . can make it happen

The first fixing bar and the second fixing bar 200 are installed on the upper surface of the base plate 100 through the connection piece, and the connection piece is located in the coupling hole 141 of the volume reinforcement 140. In the internal reinforcement block 150. It can be connected and fixed to firmly support and fix the first fixing bar and the second fixing bar 200 .

And the support block 300 may include a styrofoam endothelium 300a provided in a predetermined shape, and a primer-treated polyurea sheath 300b provided on the outer surface of the styrofoam endothelium 300a to cover the styrofoam endothelium 300a. . Specifically, a primer coating layer (not shown) may be formed on the surface of the Styrofoam endothelium 300a, and a polyurea shell 300b may be formed on the primer coating layer (not shown). The primer coating layer (not shown) can improve the physical properties of the support block by making the polyurea shell more firmly attached to the styrofoam, and supplementing the tensile strength and durability of the polyurea shell.

The primer coating layer may be formed by applying a primer and then drying it. As a material for the primer, a primer commonly used in the art may be used, for example, an ethylene vinyl acetate (EVA) resin, a polyvinyl acetate (PVAc) resin, or a combination thereof. It may include a phosphorus resin component. Since the resin component is water-soluble, it is possible to secure harmlessness to the human body and eco-friendliness.

Preferably, a liquid adhesive in which 20 to 60 wt% of a solid containing a resin component, specifically, 30 to 40 wt%, and a solvent, 40 to 80 wt%, specifically, 60 to 70 wt% is mixed may be used. As an example, the solid content may be a mixture of an ethylene vinyl acetate (EVA) resin and a polyvinyl acetate (PVAc) resin, and the solvent may be water. In this case, the EVA (Ethylene vinyl acetate: ethylene vinyl acetate) resin and the PVAc (Poly vinyl acetate: polyvinyl acetate) resin are preferably mixed in a weight ratio of 1:1 to 1.5, for example, in a weight ratio of 1:1.

When the solid content of the resin component is mixed at less than 20 wt%, there is a disadvantage that the application and drying time for forming the primer coating layer of the required thickness is unnecessarily delayed. There is a fear that the efficiency of the coating operation of the primer coating layer is lowered.

Drying may be performed by a conventional method in the art, and for example, hot air drying may be performed at 50 to 60° C. for 1.5 to 3 minutes. The thickness of the formed primer coating layer may be 0.1 to 1 mm, specifically, 0.3 to 0.7 mm, but is not limited thereto.

The polyurea shell 300b is obtained by coating and drying a polyurea resin, and may use a common component. For example, it is preferable to use a resin solution in which 20 to 30 wt% of resin solids and 70 to 80 wt% of an organic solvent are mixed. A resin composition in which 85 to 95 wt% and 5 to 15 wt% of a resin curing agent are mixed may be used, and various types of the resin curing agent may be used, but a polyisocyanate compound is a typical example.
