Description

Field of invention

[0001] The present utility model relates to the field of helmets for infants, in particular a safety helmet for infants. State of the art

[0002] Due to their still-developing coordination and lack of self-protection, infants are prone to accidental head impacts during their daily activities. Therefore, infant safety helmets play a crucial role in protecting a child's head. Currently, most commercially available baby safety helmets consist primarily of sponge material as a cushioning layer. Sponge material is widely used in safety helmets due to its low price, soft texture, and ease of molding. However, this material has significant performance limitations: its ability to cushion and absorb energy is limited, and in the case of high-speed or intense impacts, it is unable to effectively distribute or absorb the shock, thus failing to provide adequate protection for the baby's head.Non-Newtonian fluids (shear-thickening fluids) are characterized by special rheological properties: their viscosity changes under external force. In the event of sudden impacts, the material hardens rapidly and can thus effectively absorb and distribute impact forces; as soon as the impact force disappears, it returns to its soft state. Using a non-Newtonian fluid as a damping material in an infant safety helmet can significantly improve protection. However, no infant safety helmets using non-Newtonian fluids as a damping material are currently available on the market. Object of the invention

[0003] The present utility model application aims to solve the aforementioned technical problems and to provide a safety helmet for infants in which a non-Newtonian fluid is integrated as an additional damping layer.

[0004] An infant safety helmet comprises a helmet shell, a fastening strap, and a shock-absorbing element. The fastening strap is connected to the second section of the helmet shell. The helmet shell consists of a fabric and a first shock-absorbing layer embedded within the fabric. The shock-absorbing element comprises a sealing layer and a second shock-absorbing layer, the latter consisting of a non-Newtonian fluid. The sealing layer completely encloses the second shock-absorbing layer, forming a plate-shaped shock-absorbing element. This element is attached between the fabric and the first shock-absorbing layer on the inside of the helmet shell and is positioned so that it is located at least in the area of ​​the back of the wearer's head.

[0005] The safety helmet for infants according to the invention uses non-Newtonian fluid as a supplement to the conventional first damping layer. It takes advantage of the shear-thickening properties of this fluid: In the event of an impact to the back of the wearer's head, the plate-shaped structure of the damping element can distribute the impact force over a larger area. This prevents excessive point loading that could injure the relatively sensitive occipital region of the baby. Since the main body of the safety helmet still consists of the conventional first damping layer, the overall weight of the helmet is not increased excessively, thus preventing any compromise to the infant's safety.

[0006] Furthermore, the first damping layer is made of sponge material.

[0007] Furthermore, the sealing layer consists of a sealing bag made of ABS plastic, with the second damping layer located inside the sealing bag.

[0008] Furthermore, the helmet body comprises a first and a second section, the second section being ring-shaped. The first section consists of several damping strips, one side of each of which is connected to the other, while the other side is attached to the second section at a distance, creating gaps between adjacent damping strips. The damping element is attached to the damping strip that corresponds to the back of the wearer's head.

[0009] Furthermore, two fastening straps are provided, which are connected to each other to fix the safety helmet to the wearer's head. Four damping strips are provided, which are evenly attached to the second section, with two opposing strips designed as lateral damping strips, to the lower part of which the fastening strap of the second section is attached. The other two opposing strips are front and rear damping strips, each equipped with a damping element.

[0010] Furthermore, it is stipulated that no more than 100 g of non-Newtonian fluid should be contained in a damping element.

[0012] An embodiment of the safety helmet for infants according to the invention is described below with reference to the drawings.

[0013] As in the Fig. As shown in Figures 1 to 3, the infant safety helmet comprises a helmet body 1, a fastening strap 2, and a cushioning element 3. The fastening strap 2 is connected to the second section 11 of the helmet body 1. The helmet body 1 consists of a fabric 4 and a first cushioning layer 5 embedded in the fabric 4, the first cushioning layer 5 preferably being a layer made of sponge material. The fabric 4 consists of cotton fabric and / or a three-dimensional spacer fabric (3D spacer fabric), both of which are commercially available materials. The helmet body 1 is formed by encasing the first cushioning layer 5 with the fabric 4. Preferably, the 3D spacer fabric is arranged on the inside of the helmet body 1 to improve its breathability.The damping element 3 comprises a sealing layer 31 and a second damping layer 32, the second damping layer 32 consisting of a non-Newtonian fluid. The sealing layer 31 completely encloses the second damping layer 32, thus forming a plate-shaped damping element 3. This seal prevents uncontrolled leakage or flow of the non-Newtonian fluid. The damping element 3 is attached to the inside of the helmet body 1 between the fabric 4 and the first damping layer 5, thereby stabilizing the damping element 3 in its plate shape between the fabric 4 and the second damping layer 32. The position of the damping element 3 corresponds at least to the back of the wearer's head.In the event of a blow to the back of the head, the impact force can be distributed by the planar structure of the damping element 3, thus preventing excessive localized stress and therefore potential injury to the sensitive back of the head. The damping element 3 preferably contains no more than 100 g of the non-Newtonian fluid. The main part of the helmet continues to consist of the known first damping layer 5, so that excessive overall helmet weight is avoided and the infant's safety is not compromised.

[0014] Preferably, the sealing layer 31 consists of a sealing bag made of ABS plastic, in which the second damping layer 32 is located.

[0015] The helmet body 1 comprises a first section 12 and a second section 11, the second section 11 being ring-shaped. The first section 12 includes several damping strips 121, one side of which is connected to each other, while the other side is attached to the second section 11 at a distance, so that gaps form between adjacent damping strips 121 for improved ventilation. The damping element 3 is arranged on the damping strip 121 that corresponds to the back of the wearer's head.

[0016] The fastening strap 2 consists of two strips that can be connected by knotting, Velcro, or a buckle, allowing the helmet to be easily attached to the wearer's head. This improves the helmet's ease of use.

[0017] As in Fig. As shown in Figure 2, in the present embodiment four damping strips 121 are provided, which are evenly attached to the second section 11. Two opposing damping strips 121 form the lateral damping strips 1212, with the fastening strip 2 being attached to the second section 11 below the lateral damping strips 1212. The other two opposing damping strips 121 form the front and rear damping strips 1211, with the rear damping strip 1211 being provided with a damping element 3.

[0018] As in Fig.As shown in Figure 3, this embodiment also comprises four damping strips 121, which are evenly attached to the second section 11. Two opposing strips form the lateral damping strips 1212, with the fastening strap 2 attached to the second section 11 below these strips. The other two opposing damping strips 121 are the front and rear damping strips 1211, each of which is equipped with a damping element 3. This arrangement eliminates the need to distinguish between the front and back, thus preventing incorrect wearing in which the damping element 3 would fail to provide its protective effect for the back of the head.

[0019] Based on the above description and teaching, those skilled in the relevant technical field can make various modifications and adaptations to the described embodiment. Therefore, this utility model application is not limited to the specific embodiments disclosed and described above. Rather, changes and modifications based on this utility model application are also intended to fall within the scope of protection of the following claims.
