Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and in particular relates to an energy-absorbing structure for the lower connecting plate of an automotive seat frame. Background Technology

[0002] In road traffic accidents, rear-end collisions between two vehicles can cause whiplash injuries to the necks of occupants in the vehicle that was rear-ended. This type of injury is not only common, but also, due to the location of the injury, often leads to serious long-term consequences.

[0003] To prevent injuries from such accidents, existing technologies offer a variety of active and passive safety measures. Most of these measures provide structures that simply absorb impact energy, such as adding energy-absorbing mechanisms to car seats. However, most existing energy-absorbing seat structures are quite complex, require specific installation methods, and are difficult to install. Therefore, this invention proposes an energy-absorbing structure for the lower connecting plate of a car seat frame to solve the above problems. Utility Model Content

[0004] This invention, from the perspective of the practicality and safety of energy-absorbing structures in automotive seat frames, proposes an energy-absorbing structure for the lower connecting plate of an automotive seat frame, namely, the energy-absorbing component of this invention. In extreme conditions such as vehicle collisions, the energy-absorbing holes on the connecting plate deform, providing deformation space for the seat system to release energy. This facilitates the dispersion, absorption, and transmission of force, improving the overall safety of the seat. Furthermore, the structure is simple and easy to implement, aiming to solve the problems raised in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is an energy-absorbing structure for the lower connecting plate of an automobile seat frame, including a lower connecting plate, fasteners and a seat cushion side plate;

[0007] The lower connecting plate is used to connect and install the seat back adjuster. The lower connecting plate includes an energy-absorbing and receiving hole. The energy-absorbing and receiving hole deforms under extreme conditions of vehicle collision, causing the seat back to flip backward, thereby controlling the direction of seat deformation.

[0008] The seat cushion side panel and the lower connecting plate are fixedly connected by two fasteners.

[0009] Preferably, the lower connecting plate further includes a mounting rotation hole, a first connecting hole, and a second connecting hole. The mounting rotation hole is connected to the angle adjuster on the seat back. The two fasteners pass through the first connecting hole and the second connecting hole respectively to fix the seat cushion side plate to the lower connecting plate.

[0010] Preferably, the energy-absorbing receiving hole is located on one side of the mounting rotation hole and above the first connecting hole.

[0011] Preferably, when a vehicle is involved in an extreme collision, the seat frame receives a rearward pressure. When the pressure exceeds the strength tolerance of the lower connecting plate, the energy-absorbing holes in the lower connecting plate deform. After the energy-absorbing holes deform, because the pressure received by the seat frame is rearward, the seat back flips backward, thereby controlling the direction of the seat deformation.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention features energy-absorbing holes on the lower connecting plate. When a vehicle experiences a collision or other extreme conditions, the seat frame receives a rearward pressure. When this pressure exceeds the strength tolerance of the lower connecting plate, the energy-absorbing holes in the lower connecting plate deform. After the energy-absorbing holes deform, because the pressure received by the seat frame is rearward, the seat back flips backward, thereby controlling the direction of the seat's deformation. This facilitates the dispersion, absorption, and transmission of force, improving the overall safety of the seat. It also provides deformation space for the seat system to release energy, making the seat safer to use, and the structure is simple and easy to implement. Attached Figure Description

[0023] Please see Figures 1 to 3 This utility model provides a technical solution: an energy-absorbing structure for the lower connecting plate of an automobile seat frame, including a lower connecting plate 1, fasteners 2, and a seat cushion side plate 3; the lower connecting plate 1 is used to connect and install an adjuster for the seat back, and the lower connecting plate 1 includes an energy-absorbing receiving hole 14, which deforms under extreme conditions of vehicle collision, causing the seat back to flip backward, thereby controlling the direction of seat deformation; the seat cushion side plate 3 is fixedly connected to the lower connecting plate 1 by two fasteners 2.

[0024] In this embodiment, an energy-absorbing and receiving hole 14 is provided on the lower connecting plate 1. When the vehicle is involved in an extreme collision or other extreme conditions, the seat frame receives a rearward pressure. When the pressure exceeds the strength tolerance of the lower connecting plate 1, the energy-absorbing and receiving hole 14 in the lower connecting plate 1 deforms. After the energy-absorbing and receiving hole 14 deforms, since the pressure received by the seat frame is rearward, the seat back flips backward, thereby controlling the direction of the seat deformation. This is beneficial for the dispersion, absorption and transmission of force, making the entire seat safer to use. It also provides deformation space for the seat system to release energy, making the seat safer to use, and the structure is simple and easy to implement.

[0025] For further details, please refer to Figure 2The lower connecting plate 1 also includes a mounting rotation hole 11, a first connecting hole 12, and a second connecting hole 13. The mounting rotation hole 11 is connected to the seat back adjuster. Two fasteners 2 pass through the first connecting hole 12 and the second connecting hole 13 respectively to fix the seat cushion side plate 3 to the lower connecting plate 1.

[0026] In this embodiment, the mounting rotating hole 11 is connected to the seat back adjuster, and two fasteners 2 pass through the first connecting hole 12 and the second connecting hole 13 respectively to fix the seat cushion side plate 3 to the lower connecting plate 1. The fastener 2 can be a bolt, and the first connecting hole 12 and the second connecting hole 13 can be threaded holes. The fastener 2 matches the first connecting hole 12 and the second connecting hole 13.

[0027] For further details, please refer to Figure 3 The energy-absorbing receiving hole 14 is located on one side of the mounting rotating hole 11 and above the first connecting hole 12.

[0028] In this embodiment, the energy-absorbing and receiving hole 14 is located on the side of the mounting rotation hole 11 and above the first connecting hole 12. When the vehicle is involved in an extreme collision or other extreme conditions, the seat frame receives a backward pressure. When the pressure exceeds the strength tolerance of the lower connecting plate 1, the energy-absorbing and receiving hole 14 in the lower connecting plate 1 deforms. After the energy-absorbing and receiving hole 14 deforms, since the pressure received by the seat frame is backward, the seat back flips backward to control the direction of the seat deformation.

[0029] The working principle and usage process of this utility model are as follows: An energy-absorbing and receiving hole 14 is provided on the lower connecting plate 1. When the vehicle is involved in an extreme collision or other extreme conditions, the seat frame receives a backward pressure. When the pressure exceeds the strength tolerance of the lower connecting plate 1, the energy-absorbing and receiving hole 14 in the lower connecting plate 1 deforms. After the energy-absorbing and receiving hole 14 deforms, because the pressure received by the seat frame is backward, the seat back flips backward, thereby controlling the direction of the seat deformation. This is beneficial for the dispersion, absorption and transmission of force, making the entire seat safer to use. It also provides deformation space for the seat system to release energy, making the seat safer to use, and the structure is simple and easy to implement.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
