Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a 40 / 60 split-back automotive seat for the middle row with independently adjustable backrest. Background Technology

[0002] In the field of automotive seat design, the 40 / 60 split layout of the middle row seats is widely used because it can flexibly meet the needs of different numbers of passengers and the utilization of interior space. However, this layout has obvious limitations in existing technology. Currently, the 40 / 60 sections of the middle row seats generally adopt a linked adjustment method, that is, when a passenger adjusts the 40 / 60 seat back, the 60 / 60 seat back also moves accordingly. This linked adjustment mechanism leads to many inconveniences: on the one hand, when passengers need to enter the third row, the operation is cumbersome, requiring adjustment of the 40 / 60 seat back, and the movement of the 60 / 60 seat back may obstruct the passenger's entry and exit; on the other hand, this linked adjustment method may negatively affect the riding experience of passengers in the 60 / 60 seat, such as the sudden movement of the 60 / 60 seat back after adjusting the 40 / 60 seat back while the passenger is sitting, which may cause discomfort to the passengers in the 60 / 60 seat.

[0003] As people's demands for automotive comfort and convenience continue to increase, the existing 40 / 60 split-folding seat adjustment system for the middle row is gradually failing to meet market needs. Therefore, developing a 40 / 60 split-folding car seat for the middle row that allows for independent backrest adjustment is particularly necessary. Utility Model Content

[0018] The four-part seat cushion 1 is installed on the moving component, the two limiting locks 1 2 are respectively installed on the four-part seat cushion 1, the four-part backrest 3 is installed between the two limiting locks 1 2, the left unlocking component is installed on the four-part backrest 3, the six-part seat cushion 4 is installed on the moving component 2, the two limiting locks 2 5 are respectively installed on the six-part seat cushion 4, the six-part backrest 6 is installed between the two limiting locks 2 5, and the right unlocking component is installed on the six-part backrest 6.

[0019] In this embodiment, when the quarter-seat needs adjustment, the left unlocking component is pulled. The left unlocking component causes the two limit locks 2 to release the restriction on the quarter-backrest 3, and simultaneously unlocks the limit of the moving component 1. At this time, the quarter-backrest 3 can be rotated towards the side closer to the quarter-backrest 1. After the quarter-backrest 3 is rotated to a preset angle, the quarter-backrest 1 can be adjusted forward and backward by the moving component 1. When the six-seat needs adjustment, the right unlocking component is pulled. The right unlocking component causes the two limit locks 5 to release the restriction on the six-backrest 6, and simultaneously unlocks the limit of the moving component 2. At this time, the six-backrest 6 can be rotated towards the side closer to the six-backrest 4. After the six-backrest 6 is rotated to a preset angle, the six-backrest 4 can be adjusted forward and backward by the moving component 2. This solves the problems of the existing middle row four-six-seat backrest linkage adjustment method being cumbersome to operate and affecting the passenger's entry and exit from the third row and the six-seat passenger's riding experience.

[0020] Furthermore, the moving component includes two slide rails 7, two sliders 8, two floor locks 9, and an unlocking rod 10. The two slide rails 7 are mounted on the vehicle body.

[0023] In this embodiment, pulling the pull plate 11 can cause the pull cable 12 and the pull cable 2 13 to retract. The retraction of the pull cable 12 can cause the two limit locks 2 to release their restriction on the quarter-backrest 3. The retraction of the pull cable 2 13 can cause the transmission plate 14 to rotate. The rotation of the transmission plate 14 can cause the pull cable 3 15 to retract. The retraction of the pull cable 3 15 can cause the unlocking rod 10 to move, thereby releasing the restriction of the two floor locks 9 on the slider 8. When only the quarter-backrest 3 needs to be adjusted, pulling the left pull plate 16 can cause the pull cable 4 17 to retract. The pull cable 4 17 can cause the two limit locks 2 to restrict the quarter-backrest 3, thus allowing the quarter-backrest 3 to be adjusted.

[0024] Furthermore, the second movable component includes two slide rails 18, two sliders 19, two floor locks 20, and an unlocking lever 21. The two slide rails 18 are mounted on the vehicle body.
