Problems solved by technology
Since the specific position of the gear slot corresponds to a specific backrest inclination, and the number of gear slots is limited, the number of gears of the seat with adjustable backrest inclination is limited in this way, so that the backrest inclination angle The range of choices is limited, and at the same time, it cannot fully meet the needs of individuals with certain reclining angles of the seat back (for example, the seat cannot meet the reclining angle requirements between two gears)
In addition, when people adjust the inclination angle of the backrest of the seat, it is necessary to manually engage and disengage the locking part and the gear slot, and at the same time, the positional relationship between the locking part and the gear slot needs to be adjusted manually and counterpoint, so it is more laborious to operate

The invention discloses an adjustable backrest seat, which includes a backrest support and a cushion support, and an adjustment mechanism for adjusting the angle between the two. The adjustment mechanism includes a rack, the rotation axis of the backrest support and the center of the rack The axis is vertical, the rack is hinged with the backrest support, and the distance between the hinge point between the two and the rotation axis is greater than zero; the tooth block, the tooth block can engage with the rack; the positioning member relatively fixed with the seat cushion support position, the tooth The block can be set in the positioning member so as to reciprocate and slide along the first straight line, and the rack can be sleeved in the positioning member so as to reciprocate and slide along the second straight line. The two straight lines are vertical; the control mechanism used to control the sliding of the tooth block in the positioning member. The backrest adjustable seat has a wide adjustment range of the backrest inclination angle, which can fully satisfy the user's arbitrary selection of various backrest inclination angles, and improves the adaptability and comfort of the seat.
Description
technical field [0001] The invention relates to the field of daily necessities, in particular to a seat with an adjustable backrest. Background technique [0002] Seat is a kind of seat tool that is provided with backrest and cushion, and generally both sides of this seat are also provided with armrest respectively. In order to meet people's different needs for the inclination angle of the backrest when using the seat, so that the seat can meet the comfort requirements in different situations, people have designed a seat with an adjustable backrest, that is, the seat can be adjusted through the relevant adjustment mechanism. The inclination angle of the chair backrest can be adjusted according to specific needs. It can be seen that compared with non-adjustable seats, the seat with adjustable backrest has achieved a functional upgrade, which meets the different needs of different people for the inclination angle of the backrest, and greatly improves the scope of application ...
