Description

Technical Field

[0001] The utility model relates to a checking tool for an automobile seat airbag. Background Art

[0002] A car seat is a chair installed inside a car for the driver or passengers to sit on. It can be divided into single, double, and multi-person chairs according to the number of passengers. Most single car seats are equipped with airbags on both sides. Once the seat is hit sideways, the airbags can pop out quickly to reduce the physical injuries suffered by the people in the seat. After the airbag is installed on the seat, it must be tested to verify whether the airbag is functioning normally.

[0003] A gauge is a positioning fixture used to accurately fix parts to facilitate the measurement and evaluation of part size, shape, position, characteristics, quality, etc. If you want to test the airbag installed on a car seat, you must first fix the car seat on the matching gauge.

[0004] The existing matching inspection fixtures for automobile seats are inconvenient in actual use because, after the automobile seat is fixed, it cannot be moved laterally to adjust the left and right position as needed; in addition, the adaptability is also poor because the simulation body set in front of the automobile seat cannot be adjusted forward and backward to always fit in the front side of the back of the automobile seat. Since the simulation body is set to simulate the real situation of the human back leaning against the back of the seat when the human body is sitting, if the simulation body cannot fit in the front side of the back of the automobile seat, it will inevitably affect the accuracy of the airbag detection result, which needs further improvement.

[0035] A vertically arranged and rotatable adjusting screw 310 is inserted and connected at each of the four corners of the supporting plate 32 , and a threaded end of each adjusting screw 310 is inserted and screwed into the bottom plate 31 .

[0036] At least two guide rails 4 are fixed on the top of the seat frame 2. The guide rails 4 are arranged in sequence from front to back and are parallel to each other. A movable slider 6 is sleeved on each guide rail 4. Each slider 6 is fixed to the bottom of the base plate 31.

[0037] Working principle:

[0038] The bottom of the car seat 7 is placed between the two side frames 34, and the connecting plates on the left and right sides of the bottom of the car seat 7 are respectively embedded in the positioning notches 3411 on the side blocks 341 in the two side frames 34. Prior to this, it is necessary to first unscrew the two second knob screws 342 in each side frame 34. After the placement of the car seat 7 is completed, the threaded end of each second knob screw 342 is passed through a mounting hole on a connecting plate on the same side and screwed into the outer inner wall of the positioning notch 3411, thereby completing the fixation of the car seat 7.

[0039] Next, loosen the first knob screw 335 in each limit module, and then move the seat block 334 forward and backward along the length direction of the first profile tube 331, and then adjust the forward or backward inclination angle of the second profile tube 332 with the help of the third profile tube 333, so that the rear outer wall of the rear cover 36 fits the front side of the backrest of the car seat 7. The rear cover 36 will automatically adjust the inclination angle to adapt to the shape of the front side of the backrest of the car seat 7 with the help of the rotatable connection relationship between the connecting seat 35 and the end of the suspension 3310 in each support assembly 33, and then tighten each first knob screw 335 to fix the seat block 334.

[0040] Finally, the function of the airbag installed inside the car seat can be tested with the help of supporting special testing equipment.

[0041] In addition, by screwing the four adjusting screws 310 in sequence, the four corners of the support plate 32 can be driven to move upward or downward respectively according to the principle of spiral connection until the support plate 32 is leveled or adjusted to a required tilt angle.

[0042] If it is necessary to adjust the left and right position of the car seat 7, first, move the handle of the quick clamp 55 in the locking mechanism 5 to move its movable end forward, and then drive the block 53 to move forward with the help of the pin rod 52, so that each tooth 531 is disengaged from the tooth groove surface of the rack 54, and then each guide rail 4 and each slider 6 arranged on the guide rail 4 can be used to move the bottom plate 31 left and right to adjust the left and right position of the car seat 7. After the adjustment is completed, move the handle of the quick clamp 55 in the opposite direction to move its movable end backward and lock it, and then, in the same way, each tooth 531 on the block 53 is engaged with the tooth groove surface of the rack 54, thereby locking the position of the car seat 7 again to prevent it from loosening.

[0043] After the utility model completes the fixation of the car seat 7, the car seat 7 can also be moved laterally to adjust its left and right position and locked with the help of the locking mechanism 5, which is convenient for use and ensures the fixation firmness of the car seat 7 after the position is adjusted; in addition, the front and rear position of the simulation body can be simply and conveniently adjusted with the help of multiple supporting units so that it always fits the front side of the back of the car seat, thereby effectively improving the adaptability to better simulate the real situation of the human back leaning on the back of the seat, thereby ensuring the accuracy of the airbag detection result.
