[0030] Combination Figures 1 to 5 As shown, the utility model provides a rear seat back foam side surface support reinforcement structure including a foam back 1 and a felt 2.
[0031] Combination Figures 1 to 5As shown, the foam backrest 1 is formed by one-time foaming of the foam material; the felt 2 is a soft and porous fabric, the felt 2 fits the side surface of the foam backrest 1, and the shape of the felt 2 is the same as the shape of the side surface of the foam backrest 1; the foam material is impregnated into the felt 2 and the foam backrest 1 and the felt 2 are integrally formed and connected.
[0032] In this embodiment, the outer shape of the felt 2 is the same as the outer shape of the side surface of the foam backrest 1 and does not include any size limitation. It refers to a relationship similar to the same outer shape between a large rectangle and a small rectangle. Regardless of whether the sizes are the same, they are all within the description range of the same outer shape. The felt 2 with such an outer shape can ensure the uniformity of the supporting effect at various locations on the foam backrest 1, thereby improving the user experience.
[0033] In this embodiment, the porous structure inside the felt 2 is filled with foaming material, so that the felt 2 loses its deformation ability, and the felt 2 changes from soft to hard to provide a supporting effect. Since the felt 2 is soft in the initial state, the shape of the felt 2 is easier to control, thereby reducing appearance defects and improving appearance effects.
[0034] In this embodiment, the foam backrest 1 and the felt 2 are integrally formed, and the connection effect is better. The felt 2 is directly attached to the inner cavity of the foaming mold during the production process of the foam backrest 1. The pressure during the foaming molding process is used to make the foaming material penetrate into the felt 2. At the same time, the pressure will press the felt 2 tightly against the inner cavity surface of the foaming mold. In addition, the felt 2 is in a soft state at this time, which can effectively avoid the occurrence of overflow. At the same time, the foaming material and the felt 2 will fit the inner cavity of the foaming mold, which can effectively improve the smoothness of the transition between the foam backrest 1 and the felt 2.
[0035] In some embodiments, in combination Figure 1 As shown, the distance between the outer contour of the felt 2 and the outer contour of the side surface of the foam backrest 1 is equal everywhere, which is similar to the relationship between concentric large circles and small circles. The outer contour size of the felt 2 here is smaller than the outer contour size of the side surface of the foam backrest 1, ensuring the softness of the edge of the foam backrest 1 and reducing the risk of bumps and collisions for users. At the same time, the uniformity of the margins can ensure the uniformity of the supporting effect.
[0036] In some embodiments, in combination Figure 1 As shown, the distance between the outer contour of the felt 2 and the outer contour of the side surface of the foam backrest 1 is between 5mm and 20mm. If the margin is too small, the risk of bumping will increase, while if the margin is too large, the supporting effect cannot be guaranteed. The margin needs to be within a reasonable range to balance the relationship between the two.
[0037] In some embodiments, the felt 2 is made of polyester material, among which PE and PET are the most commonly used materials in actual production processes.
[0038] In some embodiments, in combination Figure 3As shown, the outer contour edge of the felt 2 is provided with a curling feature 21 . The design of the curling feature 21 is a design for enhancing the supporting effect. The curling feature 21 can increase the thickness of the outer contour edge of the felt 2 and increase the supporting strength of the felt 2 .
[0039] In some embodiments, in combination Figure 3 As shown, the curling feature 21 is perpendicular to the side surface of the foam backrest 1, and the curling feature 21 fits the surface of the felt 2 so that the thickness of the outer contour edge of the felt 2 becomes twice as thick as before, which is the simplest design. In addition, the curling feature 21 can also be cylindrical or vertical. The curling feature 21 is perpendicular to the side surface of the foam backrest 1, and the supporting effect is best when the length of the curling feature 21 is the same.
[0040] In some embodiments, the rear seat back foam side surface support reinforcement structure also includes a skin 3, which covers the outer surface of the foam backrest. The skin 3 is one of the important components of the car seat, which can protect and improve the touch of the seat and improve the user experience, while also taking into account the characteristics of beauty and easy cleaning.
[0041] In some embodiments, in combination Figure 4 As shown, the felt 2 is also provided with a positioning hole 22 and a positioning ring 23, and the positioning ring 23 is embedded in the positioning hole 22. The positioning holes 22 are evenly distributed along the edge of the felt 2, and the positioning ring 23 connects the positioning hole 22 and the skin 3. Since the felt 2 is rigid after being immersed in the foaming material, it is suitable for fixing the position of the skin 3. The skin 3 is generally directly mounted on the foam backrest 1, which is easy to deviate during use, affecting the use experience. Fixing the skin 3 can directly prevent the occurrence of the deviation phenomenon. At the same time, the felt 2 is large enough, the effective area of the fixed skin 3 is large enough, and the fixing effect is good.
[0042] In some embodiments, in combination Figure 5 As shown, the outer contour edges of the felt 2 are all provided with rounded corner features 24 connecting the edges. Since the foam backrest 1 may be creased at some positions for aesthetics or other needs, but the foam backrest 1 is soft and does not cause the risk of bumping, the felt 2 adds rounded corner features 24 at these positions to avoid the risk of bumping.
[0043] In some embodiments, in combination Figure 5 As shown, the radius of the rounded corner feature 24 is greater than 5 mm. The rounded corner feature 24 is to reduce the risk of bumping. When the size of the rounded corner feature 24 is too small, it will affect the effect of the risk of bumping. Although theoretically, the larger the size of the rounded corner feature 24, the better the effect of the risk of bumping, in order not to affect the supporting effect of the felt 2, the size of the rounded corner feature 24 needs to be reasonably designed based on the actual situation.
[0044] Working process: During the production of the foamed backrest 1, the felt 2 is attached to a specific position of the inner cavity of the foaming mold. During the molding process of the foamed backrest 1, the foaming material will naturally penetrate into the felt 2, and the foamed backrest 1 and the felt 2 will be integrally molded and connected. Since the felt 2 is soft in its initial state, the felt 2 will fit tightly into the inner cavity of the foaming mold during the molding process of the foamed backrest 1, so that the connection between the molded foamed backrest 1 and the felt 2 will present a better appearance.
[0045] The felt 2 is located on the side surfaces of the foam backrest 1 to provide support, and the two sides of the foam backrest 1 will provide certain support to the middle, so that the overall support effect of the foam backrest 1 is improved.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
