Description

Concealed headrest adjusting mechanism and seat Technical Field The utility model relates to the field of seats, in particular to a hidden headrest adjusting mechanism and a seat. Background The headrest with adjustable supporting position can be arranged at the upper end of the chair back, so that the supporting position of the headrest can be conveniently adjusted, and part of the headrest is usually movably connected at the upper end of the chair back so as to adjust the supporting position in the front-back direction or the vertical direction of the headrest, thereby meeting the use requirement. For example, in the patent CN217644858, the headrest comprises a soft headrest packet and a headrest reinforcing seat, the headrest reinforcing seat is provided with two connecting parts, the soft headrest packet is located between the two connecting parts, one end of the first connecting part is connected with the headrest reinforcing seat, the other end is rotationally connected with the second connecting part, the third connecting part is slidably sleeved on the second connecting part, and the lifting or lowering of the headrest reinforcing seat can enable the whole headrest to be adjusted in height in the upward or downward direction, but the third connecting part and the second connecting part are in an exposed state, so that the headrest is mounted on the chair back, the appearance of the chair is affected, and safety problems such as a clamping hand are easy to generate. For example, in the headrest-adjustable office chair with the publication number CN221887970, a fixed plate is fixedly arranged on the back side of the office chair, a lifting plate is slidably arranged in the fixed plate, a height adjusting device is arranged below the fixed plate on the back side of the office chair and is in power connection with the lifting plate, a front-back adjusting device is arranged on the upper portion of the lifting plate, the end part of the front-back adjusting device is connected with a headrest through an angle adjusting device, the front-back adjusting device comprises a screw rod II which is in threaded connection with the lifting plate, a hand wheel II is arranged at the end part of the screw rod II, and the headrest can be adjusted front and back through rotating the hand wheel II, but the lifting plate and the screw rod II in the patent are in an exposed state, so that the appearance is not concise, and safety problems such as clamping the like are easier to generate no matter when the height of the headrest is adjusted or adjusted front and back. Disclosure of Invention The utility model provides a hidden headrest adjusting mechanism and a seat, wherein a shielding piece is connected to a movable part, and a movable connecting mechanism formed by the movable part and a supporting part is arranged in a containing space of the shielding piece, so that the movable connecting mechanism is always arranged in the surrounding of the shielding piece when the position of a headrest is adjusted, the appearance of the seat is simplified, and the safety of the seat is improved.
