Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle seats, and particularly relates to a vehicle seat with a seat cushion that can be lifted upward. Background Art

[0002] At present, with the public's demand for the comfort of the interior space of the vehicle, the limited space inside the vehicle can no longer meet the public's needs. The "versatile space" inside the vehicle has become the mainstream demand. The seat not only needs to meet normal use but also needs to be folded or retracted when necessary to liberate a large amount of space, or serve as a rest area for pets to provide a more comfortable space.

[0003] In traditional vehicle models, the rear seat usually folds the backrest of the rear seat forward so that the back surface of the backrest is almost flush with the trunk carpet to release the X-direction space at the rear. However, for some objects that need to be placed vertically and have a large Z-direction dimension, such as pets, this scenario cannot be accommodated. Therefore, a rear seat cushion folding mechanism has gradually emerged on the market. The seat cushion folding mechanism is to keep the backrest stationary and fold the seat cushion to leave the space at the position of the seat cushion before folding. However, most of the current seat cushion folding mechanisms directly flip at the bottom end of the backrest or use a multi-link complex mechanism, resulting in little increase in the usable space after folding or high costs. Summary of the Utility Model

[0004] The utility model provides a vehicle seat with a seat cushion that can be lifted upward, aiming to solve the problems raised in the background art.

[0005] The utility model is realized as follows: a vehicle seat with a seat cushion that can be lifted upward includes a right seat cushion mounting lower plate, a seat cushion skeleton assembly, an adjuster, an unlocking assembly, and a left seat cushion mounting lower plate;

[0006] The right seat cushion mounting lower plate and the left seat cushion mounting lower plate are arranged relatively at intervals.

When the seat cushion reaches the open position, the angle adjuster 7 is internally locked, thereby realizing the locking of the seat cushion in the open position;

[0043] In the second method, when the seat is designed, the angle adjuster 7 is in the locked state. When the seat cushion needs to be lifted, the motor in the unlocking component 9 controls the connecting rod to rotate, thereby driving the seat cushion frame component 4 to rotate. At this time, the angle adjuster 7 is unlocked, achieving the unlocking effect. At this time, the seat cushion is automatically lifted, and the seat cushion frame component 4 rotates around the axis of the angle adjuster 7, driving the vehicle body support cross-bending pipe component 3 and the front-end connecting rod 2 to rotate, resulting in an angular change, realizing the automatic folding and lifting of the seat cushion. When the seat cushion reaches the open position, the angle adjuster 7 is internally locked, thereby realizing the locking of the seat cushion in the open position.
