When the quick entry function is started, the retaining mechanism can pass through the limiting part outside the sliding rail without influencing the quick entry function.
Fig. 4 is a schematic view of the initial state of the holding function of the car seat with the quick access holding mechanism of the present invention.
As shown in fig. 4, the vehicle seat having the quick entry and exit holding mechanism is in an initial state because the intermediate link 13 cannot move. When the driving member is not driven, the four-bar linkage 10 can be kept stable. The first return spring 33 and the second return spring 36 ensure that the holding mechanism 30 is not influenced by the slide slot 321 to move counterclockwise.
Fig. 5 is a schematic view of the state of the holding mechanism in contact with the position limiting member in the holding function of the car seat with the quick-entry holding mechanism according to the present invention.
As shown in fig. 5, the direction of the force applied to the locking plate 32 at this time is always not through its center of rotation, ensuring that the locking plate 32 can rotate clockwise past the stop member 40. By this effect, the easy entry link 31 also rotates clockwise, but the rotation does not affect the stability of the easy entry (VEZE) of the vehicle seat.
Fig. 6 is a schematic diagram of the initial state of the fixed-point return function of the car seat with the fast in-and-out holding mechanism of the present invention. Fig. 7 is a schematic view of the state of the holding mechanism contacting the position limiting component in the fixed point return function of the car seat with the quick in-out holding mechanism of the present invention.
As shown in fig. 6 and 7, the retention mechanism 30 will strike the stop member 40 when moving rearward, causing the lock plate 32 to move counterclockwise to the position shown in fig. 8. The locking plate 32 is now forced through its center of rotation, thereby securing the retaining mechanism 30 and preventing further rearward movement of the slide 50. This process has guaranteed that slide rail 50 can be at assigned position return VEZE, through the position of adjusting stop block 40 on slide rail 50, can satisfy different return position needs.
The rotation of the holding mechanism 30 changes the shape of the quadrangle as shown in fig. 8. At this time, if the intermediate link 13 tends to rotate clockwise by a rearward force of the seat frame 20, the movement direction of the easy entry link 31 is clockwise according to the quadrilateral principle, and is identical to the direction of the intermediate link 13, so that the seat can be withdrawn from the easy entry (VEZE) state and returned to the sitting position.
Fig. 8 is a schematic diagram of the state of the return in the fixed point return function of the car seat with the quick in-out holding mechanism of the present invention.
As shown in fig. 8, after the intermediate link 13 is rotated by a certain angle (i.e., when the easy entry VEZE process is completed to a certain extent), the slide rail unlocked by the easy entry device (VEZE) starting process should be in a locked or semi-locked state at this time.
At this time, the intermediate link 13 continues to rotate, which drives the retaining mechanism 30 to rotate clockwise until the retaining mechanism is unhooked from the outer limiting component 40 of the slide rail 50. Thereby achieving the exit of the slide 50 from the holding state.
The automobile seat can prevent the comfortable position between the seat frame and the sliding rail from being converted into the upright position through the matching use of the retaining mechanism and the limiting component. Because the limiting component is arranged on the public rail, the passenger can be reminded to adjust the seat frame from the easy-entry position to the comfortable position.
When the passenger lifts the seat frame, the easy entry link rotates, slides along the L-shaped slot on the locking plate, stops the seat frame in the upright position, and then the passenger pushes forward to the easy entry position. After the passengers enter the third row of seats, the passengers pull back the seat frame, the locking plate is blocked by the limiting component, the passengers can push the upper part of the seat frame to enable the seat frame to continuously advance to a comfortable position, and the easy-to-enter connecting rod drives the locking plate to return to the original position.
To sum up, the utility model discloses car seat with quick business turn over retaining mechanism has following advantage:
one, can realize that three rows of passengers can not make the seat reset because of the maloperation when getting into, avoid the passenger to collide with.
Two, three rows of passengers need to adjust two rows of seats return after taking a seat, can not make the seat not reach the assigned position and just return because of the too big or slide rail of sliding resistance of slide rail blocks, avoid the passenger to collide with.
Thirdly, when the seat is adjusting the VEZE return, the seat can be ensured to return when the slide rail slides to the position designated by the design, namely the fixed-point return function.
The automobile seat with the rapid in-out holding mechanism can achieve rapid in-out of the automobile seat, and is light in weight, convenient to use and low in cost.
