Description

Seat angle compensation mechanism
Technical Field
The invention relates to the technical field of seats, in particular to a seat angle compensation mechanism.
Background
Referring to fig. 1, the seat belt apparatus of the self-contained sensor compensation mechanism used in the current ABTS seat includes a retractor 100, a sensor compensation mechanism 200, a seat belt 300, and a seat belt receptacle (not shown). Referring to fig. 2 to 5, the retractor 100 is mounted on the back frame 400, one end of the seat belt 300 is retracted within the retractor 100, the other end is fixed on one side of the seat cushion frame 500 by the seat belt fixing member 310, and the seat belt socket is fixed on the other side of the seat cushion frame 500. In use, the seat belt latch 320 on the seat belt 300 is inserted into the seat belt receptacle.
The sensor compensation mechanism 200 is installed at the hinge joint of the back frame 400 and the seat cushion frame 500, and comprises a rotating part 210, a fixed part 220 and a fixed part compensation sheet 230, wherein the fixed part 220 is installed on the back frame 400, the rotating part 210 is installed on the seat cushion frame 500 through the fixed part compensation sheet 230, the fixed part 220 is connected through a retractor cable 221, the rotating part 210 rotates concentrically relative to the fixed part 220 along with the rotation of the back frame, the fixed part 220 slides relative to the fixed part compensation sheet 230, the retractor 100 is compensated through the retractor cable 221, and the working principle of the sensor compensation mechanism can be seen in the safety belt device disclosed in CN 111801251A.
Referring specifically to fig. 4 and 5, when the back frame 400 is adjusted forward, which corresponds to the rotation of the back frame 400 relative to the seat cushion frame 500, for example, the back frame 400 is adjusted forward by 15 ° relative to the seat cushion frame 500, the rotating portion 210 of the sensor compensation mechanism 200 also rotates by 15 ° along with the back frame 400, so that the angle Θ is reduced by 15 °, and the seat belt 300 in the retractor 100 can be used normally.
Referring to fig. 6 and 7, the seat belt device with the sensor compensating mechanism used in the ABTS seat described above has the following problems when applied to a zero pressure seat with ABTS function:
When the zero pressure function is adjusted, the seat cushion frame 500 and the back frame 400 are adjusted backward together, and no relative rotation occurs between the back frame 400 and the seat cushion frame 500, so that the sensor compensation mechanism 200 does not compensate the retractor 100, and the retractor 100 cannot work, so that the seat belt 300 of the retractor 100 cannot be used.
To solve the above-mentioned problems, some solutions use a seat belt device with a motor compensation mechanism 600 in ABTS seats (see fig. 8). The electric motor compensation mechanism 600 compensates the retractor 100 through the retractor cable 610, and the working principle thereof is as follows: when the backrest is adjusted or the zero pressure is adjusted, the angle of the retractor is changed, and at this time, the rotation angle of the driving motor in the electric motor compensation mechanism 600 is calculated through the module in the electric motor compensation mechanism 600, and then the retractor 100 is compensated through the retractor cable 610, so that the safety belt 300 of the retractor 100 can be normally pulled out.
However, the seatbelt apparatus of the present invention has the following problems:
1) The compensation mechanism 600 with motor has a complex structure, and the compensation mechanism can be compensated by matching with the control of a module, and the module is required to calculate the adjustment angle of the backrest in real time, so that the retractor works normally, and the requirement on the seat is high.
2) All adjustments must be electric and the motor must have a countable function, such as a ripple motor or a hall motor, etc.
Therefore, the seatbelt apparatus of the electric motor compensating mechanism 600 has a problem in that the structure and control are complicated, so that the cost is high.

The working principle of the seat angle compensation mechanism of this embodiment is as follows:
referring to fig. 24 and 25, when the seat is in the original position, the seat frame 500 does not rotate relative to the seat frame 510 to perform an angle change, and at this time, the triangle link 730 cannot rotate under the action of the seat angle sensing stay wire 712 and the first spring 740. The non-rotatable triangle link 730 prevents rotation of the fixed portion 220 of the sensor compensation mechanism 200 by the fixed portion compensator 230.
Referring to fig. 26 and 27, when the back frame 500 is independently adjusted, the triangle link 730 cannot rotate under the action of the seat angle sensing stay wire 712 and the first spring 740. The non-rotatable triangle link 730 makes the fixed portion 220 of the sensor compensation mechanism 200 non-rotatable by the fixed portion compensation plate 230, and thus the fixed portion 220 of the sensor compensation mechanism 200 is fixed by the triangle link 730, the seat cushion angle sensing stay wire 712 and the first spring 740. When the backrest is adjusted, the rotating portion 210 of the sensor compensation mechanism 200 may rotate relative to the fixed portion 220 of the sensor compensation mechanism 200. The normal function of the seat belt device with the sensor compensation mechanism for the ABTS seat is realized, and the seat belt 300 can be normally extracted.
Referring to fig. 28 and 29, when the seat cushion frame 500 rotates relative to the seat cushion frame 510 to perform an angle change, the seat cushion angle sensing stay wire fixing bracket 520 on the seat cushion frame 500 pulls the seat cushion angle sensing stay wire 712, and since the radii of the mounting points of the first end 712a and the second end 712b of the seat cushion angle sensing stay wire 712 are identical, it is possible to 1:1 the rotation angle of the seat cushion frame 500 is rotated by pulling the triangle link 730, and the rotated triangle link 730 rotates the fixed portion 220 of the sensor compensation mechanism 200 relative to the rotating portion 210 of the sensor compensation mechanism 200 by an angle equal to the rotation angle of the seat cushion frame 500 after overcoming the resistance of the first spring 740, which is equivalent to the rotation of the rotating portion 210 of the sensor compensation mechanism 200 relative to the fixed portion 220 of the sensor compensation mechanism 200. The normal function of the seat belt device with the sensor compensation mechanism for the ABTS seat is realized, and the seat belt 300 can be normally extracted.
