Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Such as Figure 1-9 As shown, the concealable seat back of the present invention includes a thin-plate-shaped rear fixing plate 2, a thin-plate-shaped front backboard 1 whose upper end is hinged to the rear fixing plate, and a thin-plate-shaped front backboard 1 whose outer end is hinged to the inner side of the backrest plate. The supporting plate 3 is formed with at least one notch, and a thin-plate-shaped limiting guide plate 4 is hinged in the notch, and the other end of the limiting guiding plate is hinged with the rear fixing plate.

[0028] It should be noted that "front" and "outside" in the present invention refer to the direction of pulling the front backboard, "rear...

Abstract

The invention discloses a concealable seat back, which comprises a rear fixed plate, a front back plate whose upper end is hinged to the rear fixed plate, a support plate whose outer end is hinged to the inner side of the back plate, and the support plate At least one notch is formed on the plate, and the limit guide plate is hinged in the notch, and the other end of the limit guide plate is hinged with the rear fixing plate. The beneficial effect of the invention is that the structure is simple, the mechanical stability is high, the front backboard has a hidden effect after being folded, and the space can be saved. At the same time, after the front backboard is pulled out, a comfortable backrest inclination and a reasonable seat depth will be formed, which conforms to the principle of ergonomic design; when the front backboard is folded, it can not only save space, but also pull out the front backboard The depth of the seat surface covered by the time is released, so that the seat surface forms a sufficient width, has the function of a bed, and can be widely used in seats or sofas, especially for occasions with high space requirements, such as small living rooms or RVs, etc. .

Description

technical field [0001] The invention relates to the technical field of manufacturing car seats and sofa seats, in particular to a concealable seat back. Background technique [0002] Seats or sofas are essential appliances in people's daily life. Although they have many forms of expression, a seat designed to conform to the physiological structure of the human body will improve the comfort of the human body. However, in the design of some caravan seats and some sofa-like seats, or because of the narrow space, or because of the need for the seat to take into account the functions of the bed, some designs reduce or cancel the inclination angle of the seat back, and some designs increase the inclination angle of the seat back. The depth of the seat surface is increased, and these defective designs sacrifice the comfort of the seat. In order to improve comfort, some RV seats and some sofa seats can only use so-called "cushions" to make up for the above defects. Especially duri...
