Fig. 1 to 7 show a preferred embodiment of a seat headrest telescopic limit adjusting structure, which comprises a headrest connecting rod 1, a guide seat 2 and a limit spring tongue 3; the headrest connecting rod 1 is connected with a guide seat 2 positioned at the rear in a sliding way; specifically, in the present embodiment, the headrest connecting rod 1 has a sliding slot 11, and the guide seat 2 is slidably connected to the sliding slot 11; a plurality of gear grooves 12 are arranged on the headrest connecting rod 1 along the height direction, and the gear grooves 12 are of a square structure; the limiting elastic tongue 3 is telescopically arranged on the guide seat 2; the head of the limiting elastic tongue 3 can be clamped into the gear groove 12 of the headrest connecting rod 1; the headrest connecting rod 1 is pulled or pressed down, and the limiting elastic tongue 3 is clamped into different gear grooves 12 so as to carry out limiting adjustment on the height of a seat headrest 6 arranged on the headrest connecting rod 1.
In this embodiment, a fixing seat 4 (for installing a seat back) is further disposed behind the guide seat 2, and the guide seat 2 is fixedly installed on the fixing seat 4. Mounting grooves are formed in the guide seat 2 and the fixed seat 4; the front part of the limiting spring tongue 3 is inserted into the mounting groove of the guide seat 2, the head part of the limiting spring tongue extends out of the mounting groove of the guide seat 2, and the rear part of the limiting spring tongue 3 is inserted into the mounting groove of the fixed seat 4. More specifically, the size of the head of the limiting elastic tongue 3 is smaller than that of the rear part of the head, so that a step structure is formed; the mounting groove of guide holder 2 also has a stair structure, and when spacing bullet tongue 3 stretches out, its stair structure can support and lean on the stair structure of the mounting groove of guide holder 2, improves structural reliability. The limiting spring tongue 3 is provided with an inner cavity, and an elastic part 5 is arranged between the inner cavity of the limiting spring tongue 3 and the fixed seat 4; in this embodiment, the elastic member 5 is a compression spring.
The upper side and the lower side of the head of the limiting elastic tongue 3 are both provided with an inclined surface 31. Through the function of the inclined surface 31, when the headrest connecting rod 1 is pulled or pressed down, the limiting elastic tongue 3 can smoothly slide out or be clamped into the gear groove 12 of the headrest connecting rod 1. Furthermore, the inclined surface of the lower side of the head of the limit latch 3 is also connected with a vertical surface 32, and the vertical surface 32 and the inclined surface 31 are matched to be clamped on the notch of the gear groove 12.
The size of the lowest gear groove 12 of the headrest connecting rod 1 is larger than that of other gear grooves, so that when the headrest connecting rod 1 is pulled to the highest gear (highest position), the limiting elastic tongue 3 can be clamped into the gear groove 12 with a larger size more deeply. The width of the inclined plane at the upper side of the head of the limiting elastic tongue 3 is larger than that of the inclined plane at the lower side of the head, and the lower side of the head is also provided with a limiting straight surface 33. As shown in fig. 7, after the head of the position-limiting latch 3 is engaged with the lowest position-limiting groove 12 of the headrest connecting rod 1, the position-limiting straight surface 33 on the lower side of the position-limiting latch 3 is engaged with the groove surface of the position-limiting groove 12, so that the headrest connecting rod 1 can be prevented from being continuously slid upward and being disengaged.
As shown in fig. 8, the invention further provides a seat, which comprises a seat headrest 6 and the seat headrest telescopic limit adjusting mechanism; the seat headrest 6 is mounted on the headrest connection rod 1.
When the headrest connecting rod is used, the headrest connecting rod 1 is pulled upwards, the limiting elastic tongue 3 stretches under the action of the elastic piece 5, slides out smoothly under the action of the inclined surface 31 of the head and is clamped into the required gear groove 12 of the headrest connecting rod 1, and the height of the seat headrest is adjusted. As shown in fig. 7, when the headrest connecting rod 1 is pulled to the highest gear (highest position), the head of the limiting elastic tongue 3 is further inserted into the gear groove 12 of larger size located at the lowest position of the headrest connecting rod 1, the limiting straight surface 33 at the lower side of the limiting elastic tongue 3 is clamped against the groove surface at the lower side of the gear groove 12, and the inclined surface 31 at the upper side thereof is clamped against the upper side of the notch of the gear groove; due to the action of the limiting straight surface 33, the headrest connecting rod 1 cannot continuously slide upwards, and can be prevented from falling off. At this time, the upper side of the position-limiting latch 3 is engaged with the shift groove 12 through the inclined surface 31 thereof, so that the headrest connecting rod 1 can still slide downward to lower the height of the seat headrest 6.
This flexible spacing regulation structure of seat headrest uses more conveniently, and the design is simpler, can require more convenient highly adjusting the seat headrest according to user demand and height, improves the use travelling comfort of seat headrest.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
