Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a sliding rail-moving middle row entry four-quarter car seat. Background Technology

[0002] As a key component of a car's interior, the design and layout of car seats significantly impact the passenger experience. With the advancement of automobiles towards intelligence and comfort, and the diversification of travel needs, the importance of middle-row seats is increasingly prominent. Middle-row seats not only affect the comfort of second-row passengers but also influence the ease of access for third-row passengers and the overall flexibility of the interior space. Current technology has several limitations in the design of middle-row seats, gradually failing to meet the diverse needs of modern family and business travel.

[0003] The existing middle-row seat design has the following problems: First, the adjustment is inflexible, making it difficult to meet the personalized needs of different passengers for seating space and posture, thus limiting the flexible use of interior space; second, it is difficult for third-row passengers to get in and out, as the inconvenience of moving the middle-row seats means that third-row passengers need a lot of space to enter and exit, affecting the convenience and efficiency of the ride. In addition, the existing seats also have shortcomings in terms of comfort, space utilization, and adaptability to various scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a sliding rail-moving third-row entry quarter-size car seat, which aims to solve the problem that existing car seats cannot be adjusted, making it difficult for third-row passengers to get up and down.

[0005] To achieve the above objectives, this utility model provides a sliding rail-moving middle row entry quarter-segment car seat, including two sliding rails, two sliders, two limit locks, a lower unlocking component, a quarter-segment seat cushion, a backrest, and a rear unlocking component;

[0006] The two sliders are slidably connected to the two slide rails respectively and are located on the two slide rails respectively. The two limit locks are respectively installed on the two sliders. The lower unlocking component is installed between the two sliders. The quarter seat cushion is installed on the two sliders. The backrest is installed on one side of the quarter seat cushion. The rear unlocking component is installed on the backrest and is connected to the lower unlocking component.

[0007] The lower unlocking assembly includes a crossbar, two transmission plates, and a pull rod. The crossbar is rotatably connected to the two sliders and is located on the two sliders. The two transmission plates are fixedly connected to the crossbar and are located on the two crossbars. The pull rod is fixedly connected to the crossbar and is located on the side of the crossbar away from the transmission plates.

[0008] The lower unlocking component further includes two torsion springs, which are respectively installed on the crossbar and connected to the two sliders.

[0009] The rear unlocking assembly includes a handle, a first pull cable, a drive plate, and a second pull cable. The handle is rotatably connected to the backrest and is located on the backrest. The pull cable is fixedly connected to the handle and to one side of the handle. The drive plate is rotatably connected to the quarter-seat cushion and is fixedly connected to the output end of the first pull cable. The second pull cable is fixedly connected to the drive plate, and the output end of the second pull cable is fixedly connected to the transmission plate.

[0010] The rear unlocking assembly further includes torsion spring two and torsion spring three. Torsion spring two is installed between the backrest and the pull handle, and torsion spring three is installed between the quarter-seat cushion and the drive plate.

[0011] This invention relates to a sliding rail-moving third-row access seat for a three-quarter seat. The two sliding rails provide mounting conditions for two sliders. When the third-row seat needs adjustment, pulling the lower unlocking component moves the two limiting locks away from the sliding rails, releasing the limiting on the two sliders. At this point, the backrest can be pushed, and the two sliders move the third-row seat cushion forward on the two sliding rails, creating space for the third-row passengers to get in and out. When unlocking the third row, pulling the rear unlocking component releases the limiting locks on the two sliders, allowing the backrest to be pushed forward and the third-row seat cushion to be adjusted. This solves the problem of existing car seats being unable to adjust, making it difficult for third-row passengers to get in and out. Attached Figure Description
