Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-diving of automobile seats, in particular to an anti-diving bracket for rear-row seats of automobiles. Background Art
[0002] With the continuous development of science and technology and the continuous improvement of people's living standards, people have more travel options, but taking a car is still the first choice for most people for short-distance travel. When the car is driving at high speed, in order to ensure the safety of passengers and the protective effect of airbags, passengers are required to fasten their seat belts when riding in a car. The correct position of the seat belt is the shoulders, chest and hips of the occupants. If the car encounters sudden brakes or crashes and stops suddenly, and the front end of the seat is not supportive enough, the passengers in the car will move forward under the action of inertia, and have a tendency to slide forward and downward. At this time, the abdominal belt of the seat belt slips off the occupant's hip bone, directly acting on the abdomen and internal organs and causing serious damage to them. The shoulder strap of the seat belt slips off and acts on the occupant's neck, and the waist belt part of the seat belt will cause great damage to the passenger's pelvis, abdomen and even chest. This posture of the passenger sliding down is called "diving."
[0003] In order to reduce or avoid the diving phenomenon and ensure the safety of the driver and rear passengers, it is necessary to install anti-diving brackets inside the car seats. However, in order to ensure the support of the brackets, the anti-diving brackets are usually made of relatively hard materials, which affects the riding comfort of the passengers.
[0004] In order to solve the above problems, we have made improvements and proposed an anti-diving bracket for the rear seats of a car. Utility Model Content

DETAILED DESCRIPTION
[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0021] Example: Figure 1-4 As shown, a rear seat anti-diving bracket for a car includes a mounting plate 1, a limiting groove 8 is provided on the upper surface of the mounting plate 1, a first support rod 2, a second support rod 9 and a central rotating rod 11 are provided on the upper surface of the mounting plate 1, a plurality of springs 3 are installed at the lower part of the first support rod 2, a connecting rod 13 is rotatably installed inside the second support rod 9, and a plurality of pressure plates 14 are installed at the lower part of the second support rod 9.
[0022] Two support frames 6 are fixedly installed on the upper surface of the mounting plate 1, and a central rotating rod 11 is rotatably installed between the two support frames 6. A plurality of connecting rods 10 are fixedly installed on both sides of the central rotating rod 11. The end of the connecting rod 10 on one side of the central rotating rod 11 is fixedly connected to the outer surface of the first support rod 2, and the end of the connecting rod 10 on the other side of the central rotating rod 11 is fixedly connected to the outer surface of the second support rod 9. The central rotating rod 11 forms a supporting point for the first support rod 2 and the second support rod 9. The connecting rod 10 connects the first support rod 2 and the second support rod 9 to keep their positions stable. When the upper part of the connecting rod 10 is subjected to uniform force, that is, when passengers are riding normally, the first support rod 2 and the second support rod 9 remain roughly horizontal, thereby ensuring the daily riding comfort of passengers.
[0023] The tops of several springs 3 are fixedly connected to the lower surface of the first support rod 2, the ends of several springs 3 are fixedly connected to the upper surface of the mounting plate 1, and the upper surfaces of the first support rod 2 and the second support rod 9 are fixedly installed with buffer pads 4 to enhance the riding experience of passengers.
[0024] A reserved groove 17 is provided inside the second support rod 9, and the connecting rod 13 is rotatably connected to the inner surface of the reserved groove 17. Torsion springs 18 are fixedly installed at both ends of the connecting rod 13, and the other ends of the torsion springs 18 are fixedly connected to the two ends of the reserved groove 17. During daily riding, the pressure plate 14 is tilted toward the inside of the bracket, and its end can only stay on the surface of the mounting plate 1 due to distance restrictions. At this time, the torsion spring 18 is twisted, and when the second support rod 9 is lifted, the pressure on the pressure plate 14 disappears, and the torsion spring 18 drives the connecting rod 13 to rotate, so that the end of the pressure plate 14 moves into the slide groove 12 and gets stuck. At this time, the second support rod 9 is lifted by the pressure plate 14 and remains lifted, the first support rod 2 drops, and the second support rod 9 is higher than the first support rod 2, preventing passengers from diving.
[0025] The outer surface of the second support rod 9 is provided with a plurality of slide grooves 12, and a plurality of pressure plates 14 pass through the slide grooves 12 upwardly and are fixedly connected to the outer surface of the connecting rod 13, and a rubber pad 15 is fixedly installed at the bottom of the pressure plate 14 to enhance the friction and stability of its support.
[0026] An oblique groove 16 is formed on the side surface of the limiting groove 8 , and when the pressing plate 14 is vertical, the end of the pressing plate 14 contacts the upper surface of the limiting groove 8 .
[0027] A plurality of mounting holes 5 are formed on the upper surface of the mounting plate 1 . Fixing bolts 7 are threadedly connected inside the mounting holes 5 . The mounting plate 1 is fixedly connected to the lower structure of the car seat through the fixing bolts 7 .
[0028] Working principle: When using this type of anti-diving bracket for the rear seat of the car, the mounting plate 1 is connected to the lower structure of the car seat through the mounting hole 5 and the fixing bolt 7 to complete the installation of the rear seat of the car. When the upper part of the connecting rod 10 is evenly stressed, that is, when the passengers are sitting normally, the first support rod 2 and the second support rod 9 remain roughly horizontal, ensuring the daily riding comfort of the passengers. During daily riding, the pressure plate 14 is tilted toward the inside of the bracket, and its end can only stay on the surface of the mounting plate 1 due to distance restrictions. At this time, the torsion spring 18 is twisted, and when the second support rod 9 is lifted, the pressure on the pressure plate 14 disappears, and the torsion spring 18 drives the connecting rod 13 to rotate, so that the end of the pressure plate 14 moves into the slide groove 12 and gets stuck. At this time, the second support rod 9 is lifted by the pressure plate 14 and remains lifted, the first support rod 2 drops, and the second support rod 9 is higher than the first support rod 2, preventing the passengers from diving.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
