Description

Technical Field

[0001] This utility model relates to the field of automotive seat structure, specifically an anti-submersion structure for automotive seats. Background Technology

[0002] Seat sag is an undesirable phenomenon in vehicle collisions, as it increases the risk of abdominal injury to occupants. During the deceleration phase of a collision, the uneven distribution of forces acting on the pelvic area (including those from the seat and seatbelt) causes the seatbelt lap belt to slip, disengage from its normal position, and slide from the pelvis towards the abdomen, directly applying the load to the abdomen and causing soft tissue injury. It is well known that there is a trade-off between seat anti-sag performance and ride comfort. Incorporating anti-sag structures into seats requires sacrificing ride comfort, which is a common technical flaw in existing seat anti-sag designs.

[0003] To address the aforementioned issues, we propose an anti-submersion structure for automotive seats, which improves upon the shortcomings of existing technologies. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an anti-submersion structure for automobile seats. In order to solve the above-mentioned technical problem, this utility model provides the following technical solution:

[0005] This utility model discloses an anti-submersion structure for a car seat, including a seat cushion. A mounting base plate is fixed to the bottom of the seat cushion, and the seat cushion also has side panels. An inner groove and a slot are formed in the center of the seat cushion. A top rod extending into the inner groove through the slot is fixed to the mounting base plate. A circular top plate is provided above the top rod. A collar that can slide up and down is fitted on the top rod, and four support rods are evenly fixed on the outer edge of the collar. The other end of the support rod is fixed to the bottom of the top plate, and a buffer spring is fitted on the top rod.

[0006] Preferably, a lower limit ring and an upper limit ring are sleeved and fixed on the top rod, the sleeve is located between the lower limit ring and the upper limit ring, and the buffer spring is located between the sleeve and the lower limit ring.

[0007] Preferably, a limiting plate is also fixed to the top of the top rod, and the limiting plate is located below the center of the top plate.

[0008] Preferably, a gap of 3-5mm is left between the limiting plate and the top plate.

[0009] Preferably, the collar rests on the bottom of the upper limit ring.

[0010] Preferably, the top rod is tilted toward the center of the seat cushion.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] By creating an inner groove within the seat cushion and incorporating an inclined push rod, push plate, collar, and buffer spring within this groove, the push plate is positioned inside the seat cushion, thus avoiding any impact on seating comfort. When the vehicle experiences a frontal impact or emergency braking, the passenger's buttocks slide downwards and forwards on the seat cushion. The passenger's buttocks press down on the seat cushion, and once the cushion contacts the push plate, the push plate lowers the collar, compressing the buffer spring and providing excellent cushioning. Simultaneously, a limiting plate holds the push plate in place, preventing it from slumping excessively, thereby preventing the passenger from sliding forward and downwards significantly. This anti-submersion structure for car seats effectively cushions the passenger's submersion action, shortens the descent distance, and prevents the seatbelt and lap belt from dislodging from their normal positions, effectively protecting the passenger and overcoming the shortcomings of existing technologies, thus improving practicality.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example

[0018] like Figure 1-2As shown, an anti-submersion structure for a car seat includes a seat cushion 1, a mounting base plate 2 fixed to the bottom of the seat cushion 1, and side panels 3 on the seat cushion 1. An inner groove 4 and a slot 5 are formed in the center of the seat cushion 1. A top rod 6 extending through the slot 5 into the inner groove 4 is fixed on the mounting base plate 2. A circular top plate 7 is provided above the top rod 6. A sliding collar 10 is fitted on the top rod 6, and four support rods 12 are evenly fixed on the outer edge of the collar 10. The other end of the support rod 12 is fixed to the bottom of the top plate 7. A buffer spring 11 is fitted on the top rod 6. The overall anti-submersion structure for the car seat can effectively buffer the submersion movement of the passenger, shorten the descent distance, and prevent the seat belt and lap belt from coming out of their normal use position, thus effectively protecting the passenger.

[0019] In this embodiment, a lower limit ring 8 and an upper limit ring 9 are sleeved and fixed on the top rod 6. The collar 10 is located between the lower limit ring 8 and the upper limit ring 9, and the buffer spring 11 is located between the collar 10 and the lower limit ring 8. By using the limit rings to limit the buffer spring 11 and the collar 10, large-scale lifting and lowering can be avoided, which can shorten the descent formation and effectively buffer the descent force.

[0020] In this embodiment, a limiting plate 13 is also fixed to the top of the top rod 6. The limiting plate 13 is located below the center of the top plate 7 and is used to prevent the top plate 7 from sinking, thereby preventing the passenger from sinking.

[0021] In this embodiment, a 3-5mm gap is left between the limiting plate 13 and the top plate 7 to provide a buffer space.

[0022] In this embodiment, the collar 10 is placed on the bottom of the upper limit ring 9 to limit the collar 10.

[0023] In this embodiment, the top rod 6 is tilted towards the center of the seat cushion 1, which allows the top plate 7 to be perpendicular to the passenger when it is lowered, increasing reliability.

[0024] The principle and advantages of this utility model: After the passenger sits on the seat cushion 1 and fastens the seat belt, when the vehicle is hit from the front or brakes suddenly, the passenger's buttocks slide downward and forward on the seat cushion 1. At this time, the passenger's buttocks press down on the seat cushion 1. After the seat cushion 1 contacts the top plate 7, the top plate 7 presses down the collar 10 and slides down. The buffer spring 11 is compressed, which buffers the downward force of the passenger and provides a good buffering effect. When the top plate 7 descends to contact the limiting plate 13, the limiting plate 13 holds the top plate 7 and prevents it from descending too much, thereby preventing the passenger from sliding downward and forward too much. The car seat anti-submersion structure with this structure design can effectively buffer the passenger's submersion action, shorten the downward stroke, and prevent the seat belt and waist belt from leaving the normal use position. It can effectively protect the passenger and improve practicality.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
