Embodiment Construction

[0032] Figure 4 It is a schematic view showing the seat structure in one embodiment of the present invention. The illustrated seat structure is a seat structure body on children's appliances such as a stroller, a baby frame, and a child seat, and has a seat plate seat plate 10 made of a rigid material and a backrest plate 11 that is rotatably connected to the seat plate 10 by a shaft. The seat structure can be switched into a chair shape and a bed shape by adjusting the inclination angle of the backboard 11 . Figure 4 Indicates bed form.

[0033] As shown in the figure, a bridging portion 13 is disposed on a bent portion (connecting portion) between the seat plate 10 and the back plate 11 . The bridging portion 13 is preferably made of a thin plate-like material that is resilient to bending force, and its one end 13a is connected to the seat plate 10 by an adhesive or the like. The other end 13b of the bridging portion 13 can be a free end, which can slide on the backboar...

Abstract

A seat structure includes a seat plate, a backrest plate adjustable in inclination angle, and a bridging member covering up a flexion portion between the seat plate and the backrest plate for bridging the seat plate and the backrest plate smoothly. The bridging member is a member shaped like a thin flat plate having a flexural elasticity and stably supports a baby's buttocks while dispersing a body pressure with its entire surface. This structure can provide such a seat structure that can prevent local loads from acting on the buttocks both in the form of a bed and in the form of a chair.

Description

technical field [0001] The present invention relates to a seat structure with a seat and an adjustable backrest, in particular to a seat structure suitable for children's appliances. Background technique [0002] Generally, the inclination of the backrest of a seat on a child's appliance such as a stroller, a baby frame, a child seat, etc. is adjustable. For the children's utensils to be put into the newborn baby, it is necessary to realize a bed shape in which the backrest can be tilted back into a substantially horizontal shape. There are also children's appliances corresponding to children's development stages on the market, which can be switched between chair shape and bed shape. [0003] figure 1 A diagram showing a part of a child's appliance seat transformed into a bed shape viewed from above. The seat is composed of a seat portion 1 and a backrest portion 2 with an adjustable inclination angle. The seat portion 1 and the backrest portion 2 are rotatably connected...
