Abstract

The utility model relates to a seat with a foaming and ventilating structure, which is mainly composed of the combination of a pillow and an inner sleeve block, wherein, the pillow is integrally formed with and is concavely inwards provided with a sleeve slot, and the surface of the pillow is provided with a plurality of upper air holes which penetrate into the sleeve slot at the bottom. The inner sleeve block is also provided with a plurality of lower air holes which penetrate to the bottom, the inner sleeve block except the lower air holes is provided with a plurality of convex columns at intervals, and the region between the convex columns and the surface of the inner sleeve block forms a plurality of air storing chambers which can store air and communicate the upper and the lower air holes mutually, and accordingly, the seat of the utility model can be more durable, more permeable to air and fit for the ergonomics.

Description

Seat with foamed material inlay and ventilating structure

The utility model belongs to cushion, the improvement project of the foaming body ventilating structure of No. 189407 thing to sit on of particularly Chinese utility model patent.

For former female case, this case creator still constantly revises design in addition and makes real product test after application and getting permission patent, finds that original bill is constructed to still have that can to improve part as follows:

By the foaming body ventilating structure of female case thing to sit on provide can refrigerant textural association and structure design ventilative, that improve traditional thing to sit on shortcoming be for: 1. connect perforation is established again on the little air-vent established again and the block set big air-vent on the cushion block behind cushion block and block set fit, make big or small air-vent intersect and put extremely and intensive conducting formation air receiver gas collection body, see Fig. 1, when thing to sit on is stressed, the size air-vent reaches refrigerant effect because of compression makes gas ejection in the hole; The design that is an accumulation gas and conducting really can be brought into play the purpose effect, yet, still have creation idea to design the structurally improved possibility that effect is more promoted again according to original bill.2. pack into by a cushion block and form a complete seat cushion in the block set, the contact-making surface of this seat cushion and human body is the pad groove end face on the block set of cushion block surface and cushion block periphery of central authorities, see Fig. 3, therefore cushion block surface and the seam of filling up the groove end face must be arranged on this contact-making surface, make seat cushion the structure weakness when load-bearing, occur.3. when seat cushion was subjected to external force, the cushion block of this external force through being contacted and pad groove reached the block set under it again, gave birth to deformation by the inner carrying of whole block set; Therefore when thing to sit on was subjected to external force, the inner stressed depression together of whole block set can't be offered an explanation the application of force size of each point.

The purpose of this improvement case is a continuity original bill creation idea, remake the design improved of an innovation, with better structure, make that whole seat cushion is more durable, can execute the body curve change shape and hold the gas ability, the conducting effect is better, and is more refrigerant ventilative, durable and meet the purpose of ergonomics to reach.

Content of the present utility model is to comprise a base and one li cover piece, this base be one-body molded and its in be arranged with a grooving, the base surface need be according to configuration design and is interval with on fusiform thing to sit on shape and its that most to go up air-vents gradually big from top to bottom from the aperture with the inclined-plane, connects to the grooving of bottom;

This cover piece is one-body molded, air-vent is from top to bottom gradually little from the aperture with the inclined-plane down to which is provided with majority, connect to the bottom that is the plane, be interval with most projections on the cover piece in beyond the following air-vent, and make between this projection with the lining sheath block block on the zone form some air receivers.

The utility model has the advantages that:

1. the following air-vent of establishing again on last air-vent that perforation is established again on the integrated base and the lining cover piece is behind base and cover piece fit, and the gas in the air-vent must be borrowed up and down, by the mutual conducting of formed air receiver between the projection of establishing again on the cover piece of lining; When thing to sit on was subjected to external force, air-vent sprayed because of compression makes the gas in the hole up and down, reaches refrigerant ventilative effect.

Base be one-body molded and be sleeved in outside the cover piece, when thing to sit on was subjected to external force, the surface is not given birth to because of jointless existence and broken, and was more durable.

3. the projection of establishing again on the cover piece in, independent each other kenel; When thing to sit on is subjected to external force, through the base of top be depressed into the below in establish again on the cover piece projection the time, independent mutually because of projection, the big young pathbreaker of the compressive deformation of each projection is to make the change of thing to sit on shape can meet the curve of human body according to each point application of force size.

4. the air receiver that forms between projection, the effect of the ability of accumulation gas and conducting air-vent, all more female case is better.

The novel embodiment of the utility model is as shown in drawings:

Fig. 1 is the profile of former female case embodiment.

Fig. 2 is the three-dimensional combination figure of the utility model embodiment.

Fig. 3 is the three-dimensional exploded view of former female case and the utility model embodiment.

Fig. 4 is the design sketch of looking up of base of the present utility model.

Fig. 5 be of the present utility model in the cover piece stereogram.

Fig. 6 be the utility model embodiment in the cover piece solid and generalized section.

Fig. 7 is the schematic diagram of the utility model embodiment.

The figure number explanation:

Base 10, last air-vent 11, grooving 12, lining cover piece 20, following air-vent 21, projection 22, air receiver 23.

Shown in Fig. 2,3, be general complete seat cushion after the utility model combination, and include a base 10 and one li cover piece 20 2 part, wherein:

Base 10 is one-body molded and in the interior grooving 12 that is arranged with, the profile on surface designs according to need to be fusiform seat cushion shape and to be interval with most air-vents 11 of going up on it and connects to the grooving 12 of bottom.

In the cover piece 20, be one-body molded, which is provided with most air-vents down 21 and connect, be interval with most projections 22 of independent kenel each other on the cover piece 20 in beyond air-vent 21 down, and the zone of overlapping on 20 of the pieces in 22 of projections and lining forms some air receivers 23 to the bottom.

See also shown in Figure 6, the solid and the generalized section of cover piece 20 in the utility model embodiment, the projection of establishing again on the cover piece 20 in this 22, cause is independent kenel each other, thus when being subjected to external force, thing to sit on reaches cover piece 20, when overlapping projection 22 loads of contact cushion cover 10 bottoms on the piece 20 by the lining, each independently projection 22 can vary in size in response to the each point application of force, and be different deformation in response to degree, make thing to sit on to change shape, to meet ergonomics with the body curve.

Please consulting shown in Fig. 7 A, is the schematic diagram of the utility model embodiment again, but by projection 22 formed air receiver 23 accumulation gases and make upper and lower air-vent mutual conduction, makes the gas permeability of seat cushion better.In addition, shown in Fig. 7 B, the utility model is to be the whole thing to sit on stress surface that contacts with human body with base 10 surfaces; These integrated base 10 surfaces have no any seam, and durability is greatly improved.

In sum, this case creator is at the deformation mode of gas permeability, durability and the pressurized of former female case structure, in continuity creation idea and the original bill function is constant innovates a more progressive improvement design down, enable to meet ergonomics, more durable and more refrigerant ventilative.
