Adjustable seat

This creation relates to a seat, in particular an adjustable seat that can change the relative position between the back pad and the seat cushion in accordance with the height of the human body.

The relative position of the back cushion and the seat cushion of the general seat is not adjustable, and it is difficult for the occupants of different heights to achieve the same level of comfort; especially for school-age children, the degree of height change is quite fast and unpredictable, and often occurs : After the parents specially tailored an expensive seat for them, it was found that the child could not get a comfortable ride from the original seat due to the change of height. If it was discarded, it would be wasteful. However, if you continue to use it, it will affect your sitting posture and cause adverse effects on your body. To this end, the creator has previously filed a patent for the "Adjustable Seat Device" No. 100205211, which is designed to adjust the relative position of the back cushion and the seat cushion of the seat to accommodate the users of different heights. The sitting position is supported by the best position, which has not only been well received from the consumer's reputation, but also won the awards in numerous children's furniture exhibitions or competitions.

The only drawback in the technical content disclosed in the above patent is that the bracket supporting the seat is a double-tube design with a spacing between the two tubes and a slightly thinner structure. Weak, so it is easy to twist and deform after being stressed. Especially when the seat cushion is adjusted in position, if the tube body of the bracket seat is deformed, it will hinder the adjustment stroke. In addition, the support frame of the support cushion must pass through the sleeve. Slewing on the pipe body of the bracket also causes disadvantages in the assembly alignment, especially the overall components are large, the production cost is high and the stock is not easy to stock, and there is still room for improvement.

In order to improve the problems existing in the prior art, the present invention specifically proposes a novel "adjustable seat" design, including a main bracket, a bracket, a guide rod, a back pad, a slider, a seat cushion, and a base. a first fixing bolt and a second fixing bolt, wherein the main bracket and the auxiliary bracket are both a triangular tubular body, and the surface of the main bracket is provided with a plurality of positioning holes arranged in the axial direction, the pair The bracket has a connecting bracket that is sleeved in the main bracket, and has a slot at one end and a triangular sleeve that points in the direction of the seat cushion, and the other end of the main bracket is connected to the base; the back pad is connected to the guide rod The guiding rod is a triangular tube body, and the surface is provided with a plurality of fixing holes arranged in the axial direction, which are movably penetrated into the sleeve, and the sleeve also has a first locking hole corresponding to the guiding rod. a fixing hole is locked with the first fixing bolt; the seat cushion is supported on the sliding rod, and one end of the sliding rod is connected with a sliding seat to be movably sleeved on the outside of the main bracket, and the sliding seat is further Having a second keyhole corresponding to the main bracket A positioning hole, and with a second fixed locking pin. The back pad is interlocked by the guide bar, and can change its position in the direction in which the seat is restrained, and the slide joint movable seat moves on the main bracket between the sleeve and the base. In this way, the beneficial effects and creative purposes that this creation can achieve include:

1. The back pad is interlocked by the guide bar, which can change its position in the direction in which the seat is restrained. The slide seat linkage seat is moved between the sleeve and the base on the main bracket, so that the relative position between the back cushion and the seat cushion is adjustable, and is more suitable for people of different heights or when the sitting posture is changed.

Second, including the main bracket, the auxiliary bracket, the guide rod, and the sleeve are all triangular tubes, which are more structural than the prior art, and are more conducive to alignment, assembly and mass production; especially in the sub-bracket and the sleeve The joint portion, through the slotted design of the sub-bracket, has a larger joint area with the sleeve of the triangle tube, and the structure thereof will be more stable.

In addition, the outer part of the sleeve and the auxiliary bracket are covered by a sheath, so as to avoid damage caused by improper external force at the joint between the two, and a corresponding hole on the sheath is located on the sleeve. A locking hole; and when assembling, the sliding seat can be sleeved outside the main bracket, and then the connecting bracket can be inserted into the main bracket to fix the auxiliary bracket connected with the sleeve, which is more convenient.

In addition, a sliding mechanism is further connected between the sliding bar and the seat cushion, the sliding mechanism includes a sliding frame, a guiding seat and a set of elastic fixing bolts; wherein the guiding seat is fixed on the sliding bar, the sliding frame is fixed The seat is coupled to the seat cushion at the bottom of the seat cushion, and a pair of slide rails are disposed on the slide frame and include two sides of the guide seat, so that the slide frame can slide on the guide seat to change the relative position of the seat cushion.

In addition, a plurality of axially arranged bolt holes are disposed on one side of the sliding rod, and a sliding plate on a corresponding side of the bolt holes has a positioning plate, and the positioning plate has at least one through hole corresponding to the outer side of any of the bolt holes. And a fixing bracket is connected to the positioning plate, the mounting bracket has a pair of guiding holes located in the through hole, and a fixing bolt is provided between the fixing frame and the positioning plate. In a normal state, one end of the fixing bolt extends into the positioning plate. Go into the perforation and enter into any of the bolt holes to interfere with it so that the position of the seat cushion is fixed.
