Description

A kind of cushion frame

Technical field

The utility model relates to field of traffic, particularly a kind of cushion frame.

Background technology

Seat is important interior trimming parts occupant and vehicle body linked together in the vehicle, and its safety and traveling comfort etc. come into one's own day by day.Cushion frame as supporting chair plays very important effect in whole armchair structure, the planform of cushion frame will determine the planform of seat entirety, at present, seat on the market, the backrest frames of its cushion frame and attic base skeleton are not integrated, be assembled after needing multiple part to process respectively, complex manufacturing technology, and assembling is complicated, its production process has pollution to environment, cannot recycle after discarded, simultaneously, because backrest frames and attic base skeleton are not integrated, therefore, be difficult to process the complex-curved cushion frame having and meet human engineering, thus cause the comfort level of seat inadequate, in addition, cushion frame all adopts metal material to make, and therefore, weight is large, and strength-to-density ratio is low, and rigidity is high, and elasticity is poor, reduce further the comfort level of seat.

At present, also have composite material to prepare shaping cushion frame on the market, but also need between its backrest and attic base to be connected by assembling, therefore, easily there is breakage in connecting portion.

Utility model content

The utility model aims to provide and a kind ofly meets human engineering and lightweight, that strength-to-density ratio is high, assembling is simple, rigidity is moderate, elasticity is good cushion frame.

A kind of cushion frame described in the utility model, comprise by the integral formed cushion frame containing backrest and attic base of multilayer continuous glass-fiber plastic sheet, arc-shaped transition district is had, its arc range 35 ° ~ 55 °, described backrest undulate between described backrest and attic base, its wave peak width is 200 ~ 450mm, waviness height is 40 ~ 100mm, trough width 200 ~ 450mm, and the trough degree of depth is 40 ~ 100mm, described attic base edge is the arc of indent, its arc range 65 ° ~ 80 °.

A kind of cushion frame described in the utility model, because cushion frame is integral formed by multilayer continuous glass-fiber plastic sheet, be connected by arc-shaped transition district one between its backrest with attic base, avoid after processing backrest and attic base respectively and connected as one by attaching parts again, not only save processing technology, the junction that also effectively prevent backrest and attic base is damaged; Simultaneously, because cushion frame adopts multilayer continuous glass-fiber plastic sheet compound one-body molded by this kind of specific process technology, therefore, the cushion frame machined has good mechanical property, and it is lightweight, strength-to-density ratio is high, and rigidity is moderate, elasticity is good, and the thickness of the cushion frame of one machine-shaping is identical everywhere, thickness is even, further ensures cushion frame and has good mechanical property; This kind of cushion frame meets human engineering, the corrugated curve of its backrest can fit with the curve of human body head to back, use more comfortable, the edge of its attic base indent can avoid user's buttocks to leave attic base because rocking in automotive operation, in addition, because cushion frame is directly formed by integral forming process, therefore, without the need to assembling, avoid the problem that when multiple parts assemble, precision is low, this kind of cushion frame can also be recycled.

Detailed description of the invention

A kind of cushion frame, as shown in Figure 1 to Figure 3, comprise by the integral formed cushion frame 6 containing backrest and attic base of multilayer continuous glass-fiber plastic sheet, arc-shaped transition district 3 is had between described backrest 1 and attic base 2, its arc range 35 ° ~ 55 °, as 35 °, 45 ° or 55 ° etc., described backrest undulate, its crest 4 width is 200 ~ 450mm, as 200mm, 300mm, 430mm or 450mm etc., wherein 430mm is optimal selection, crest 4 is highly 40 ~ 100mm, as 40mm, 70mm, 94mm or 100mm etc., wherein 94mm is optimal selection, trough 5 width 200 ~ 450mm, as 200mm, 300mm, 430mm or 450mm etc., wherein 430mm is optimal selection, trough 5 degree of depth is 40 ~ 100mm, as 40mm, 70mm, 94mm or 100mm etc., wherein 94mm is optimal selection, described attic base 2 edge is the arc of indent, its arc range 65 ° ~ 80 °, as 65 °, 70 ° or 80 ° etc.

Between described multilayer continuous glass-fiber plastic sheet, ply stacking angle is the combination between 0 ° 45 ° 90 °, as the combination of 90 °/0 °/45 °/90 °/0 °/90 °/45 °/0 °/90 °, thus effectively ensure that cushion frame 6 has excellent mechanical property, uniform force in all directions.

The thickness of described individual layer continuous glass-fiber plastic sheet is 0.25mm ~ 0.35mm, as 0.25mm, 0.30mm or 0.35mm etc., the glass fiber content of described individual layer continuous glass-fiber plastic sheet is 40% ~ 70%, as 40%, 55% or 70% etc., described cushion frame 6 thickness is 2mm ~ 6mm, as 2mm, 3.15mm, 4mm or 6mm, can ensure that the seat of machine-shaping has good mechanical property.

Trough 5 place of described backrest 1 is provided with visual window 7, not only has ornamental, and also person easy to use turns round and checks last case by visual window 7.

Described continuous glass-fiber plastic sheet material is the thermoplastic plastics such as PP, PA or PE.
