Description
Technical Field
The invention relates to the technical field of automobile seat cushions, in particular to foam for an automobile seat with ventilation holes.
Background
At present, a vehicle seat mainly comprises a supporting framework, foam and a face cover, wherein the foam is mainly used for enabling passengers to sit in the most safe possible position in the vehicle seat, and is also used for improving the comfort of the seat, relieving collision impact force, protecting the human body and tools from being damaged, and the foam is the seat cushion foam of various vehicles such as automobiles with the largest consumption. In general, a seat cushion is comfortable to sit on, can reduce fatigue, is softer, is better in general, but is too soft to cause a sticky feeling in the seat, is inconvenient to move the body to change the posture, is too hard, and is reduced in comfort, so that various manufacturers improve on adjusting the softness thereof to obtain an optimal effect. At present, production factories respectively related to foam cushion materials in China all adopt cushion materials with the same density and the same rebound rate, but the foam cannot well solve the problems, and ventilation holes formed in the traditional seat foam after deformation are very easy to be blocked, and the ventilation property is poor.
Disclosure of Invention
In order to solve the technical problems, the invention provides foam with ventilation holes for an automobile seat.
The technical proposal is as follows: the foam for the automobile seat with the ventilation holes is characterized in that: the soft bearing layer is arranged in a layered manner from bottom to top, the upper part of the hard bearing layer is tightly connected with the lower part of the transition layer through a first fabric layer, and the upper part of the transition layer is tightly connected with the lower part of the soft improvement layer through a second fabric layer;
the soft improvement layer comprises N soft supporting blocks which are arranged in a rectangular array shape, the lower parts of the soft supporting blocks penetrate through the second fabric layer to be tightly connected with the transition layer, each soft supporting block comprises X supporting triangular prisms which are vertically arranged, the X supporting triangular prisms are arranged in an annular array shape to form the soft supporting blocks, the X annular array centers of the supporting triangular prisms form ventilation channels, ventilation holes are formed in the hard bearing layer and correspond to the ventilation channels, and the ventilation holes upwards penetrate through the transition layer and then are communicated with the corresponding ventilation channels.
The hard bearing layer with the harder bottom layer mainly plays a role in supporting and bearing, the soft improvement layer with the softer upper layer is directly contacted with passengers, the touch feeling is softer and more comfortable, the riding feeling is better, and the soft improvement layer with the softer lower layer can play a certain role in protecting the passengers in the riding process, especially in accidents, so that the passengers are prevented from being injured; in addition, the soft supporting blocks are arranged in an annular array shape, so that the ventilation channel in the center of the soft supporting blocks is not blocked after being compressed and deformed, ventilation effect of the ventilation holes can be ensured to be always exerted, ventilation of the seat foam is greatly improved, and particularly, the seat is fresh and cool in body feeling and ventilation in hot summer.
As preferable: and all the supporting triangular prisms of the same soft supporting block are provided with a side edge opposite to the center of the annular array. By adopting the design, the support triangular prism is opposite to the center of the array through the side edges, and the deformation of the side edges is far greater than that of the side edges when the support triangular prism is deformed, so that the ventilation channel in the center of the support triangular prism can be prevented from being blocked all the time even if the support triangular prism is greatly deformed.
And the X is four, and the four supporting triangular prisms are in a ring array shape and enclose a tetrahedron shape to form the soft supporting block. By adopting the scheme, the appearance is attractive, and the distance between adjacent soft supporting blocks is controlled during processing conveniently.
The distance between the adjacent soft supporting blocks is equal to the distance between the adjacent supporting triangular columns of the same soft supporting block. By adopting the design, deformation yielding channel widths between adjacent soft supporting blocks and between adjacent supporting triangular columns are always ensured, each soft supporting block is uniformly stressed when in riding, passengers cannot generate a suspension fall feel, and the supporting effect is better.
The hardness of the transition layer is between the hardness of the hard bearing layer and the hardness of the soft improving layer. By adopting the scheme, the transition layer plays a role in transition connection between the hard bearing layer and the soft improvement layer, the bonding between the adjacent layers is firmer, the stripping is not easy, and the processing difficulty can be reduced.
The first and second fabric layers are made of non-woven fabrics with gram weight of 35-45g/m 2 。
The thickness of the front part of the hard bearing layer is smaller than that of the rear part of the hard bearing layer, the thickness of the thinnest part of the hard bearing layer is larger than 20mm, the thickness of the transition layer is larger than 10mm, and the thickness of the soft supporting blocks is larger than 30mm. The thickness of the hard bearing layer is thicker, which is favorable for improving the strength of the whole seat foam, and the thickness of the soft supporting block is thicker than the thickness of the hard bearing layer, which is favorable for improving the riding comfort.
The middle part and the rear portion of the hard bearing layer are provided with the soft supporting blocks, the front portion of the hard bearing layer is provided with the leg supporting blocks, and the upper surfaces of the leg supporting blocks incline from front to back gradually towards the soft supporting blocks. By adopting the scheme, the leg supporting part slightly lifts the legs of the passenger upwards, and the uncomfortable feeling of sedentary sitting is relieved.
The beneficial effects are that: the invention has the beneficial effects that the hard bearing layer with the harder bottom layer mainly plays a role in supporting and bearing, the soft improvement layer with the softer upper layer is directly contacted with passengers, the touch feeling is softer and more comfortable, the riding feeling is better, and the soft improvement layer with the softer bottom layer can play a certain role in protecting passengers in the riding process, especially in accidents, so as to prevent the passengers from being injured; in addition, the soft supporting blocks are arranged in an annular array shape, so that the ventilation channel in the center of the soft supporting blocks is not blocked after being compressed and deformed, ventilation effect of the ventilation holes can be ensured to be always exerted, ventilation of the seat foam is greatly improved, and particularly, the seat is fresh and cool in body feeling and ventilation in hot summer.
