Abstract
The utility model provides a chair framework, because the chair framework who accomplishes, is processed respectively by the compound integrated into one piece of the fine plastics lamella of the continuous glass of multilayer by back skeleton and seat dish skeleton consequently has good mechanical properties, its light in weight of, the specific strength is high, and rigidity is moderate, and the pliability is good, and simultaneously, the back skeleton that processing was accomplished and the thickness of seat dish skeleton are the same everywhere, and thickness is even, has guaranteed further that chair framework has good mechanical properties.
Description
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, 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, current 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.
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 backrest frames integral formed by multilayer continuous glass-fiber plastic sheet respectively and attic base skeleton, described backrest frames undulate, its wave peak width is 200 ~ 450mm, waviness height is 40 ~ 100mm, trough width 200 ~ 450mm, the trough degree of depth is 40 ~ 100mm, the bottom of backrest frames two side ends is respectively arranged with the first symmetrical connecting bore, the one side of described attic base aggregate and human contact is arc shape low after front height, radian is 55 ~ 65 °, attic base skeleton two side ends bends downwards, the end of its both sides bending edge is respectively arranged with the second connecting bore matched with the first connecting bore in backrest frames corresponding sides, attaching parts passes the first connecting bore and second connecting bore of corresponding setting, backrest frames and attic base skeleton are connected as one.
A kind of cushion frame described in the utility model, because backrest frames and attic base skeleton are integral formed by multilayer continuous glass-fiber plastic sheet respectively, therefore, the cushion frame machined has good mechanical property, it is lightweight, strength-to-density ratio is high, and rigidity is moderate, and elasticity is good, simultaneously, the thickness of the backrest frames machined and attic base skeleton is identical everywhere, and 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 frames can fit with the curve of human body head to back, use more comfortable, in addition, because backrest frames and attic base skeleton are directly formed respectively by integral forming process, therefore, assembly precision is high, avoids the problem that when multiple parts assemble, precision is low.

Detailed description of the invention
A kind of cushion frame, comprise backrest frames 1 integral formed by multilayer continuous glass-fiber plastic sheet respectively and attic base skeleton 2, described backrest frames 1 undulate, its wave peak width is 200 ~ 450mm, as 200mm, 300mm, 430mm or 450mm etc., wherein 430mm is optimal selection, waviness height is 40 ~ 100mm, as 40mm, 70mm, 94mm or 100mm etc., wherein 94mm is optimal selection, trough width 200 ~ 450mm, as 200mm, 300mm, 430mm or 450mm etc., wherein 430mm is optimal selection, the trough degree of depth is 40 ~ 100mm, as 40mm, 70mm, 94mm or 100mm etc., wherein 94mm is optimal selection, the bottom of backrest frames (1) two side ends is respectively arranged with symmetrical the first connecting bore (3), described attic base aggregate (2) is arc shape low after front height with the one side of human contact, radian is 55 ~ 65 °, as 55 °, 60 ° or 65 ° etc., wherein 60 ° is optimal selection, attic base skeleton (2) two side ends bends downwards, the end of its both sides bending edge (4) is respectively arranged with the second connecting bore (5) matched with the first connecting bore (3) in backrest frames (1) corresponding sides, attaching parts passes the first connecting bore (3) and second connecting bore (5) of corresponding setting, backrest frames (1) and attic base skeleton (2) are connected as one.
Between described multilayer continuous glass-fiber plastic sheet, 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 backrest frames 1 and attic base skeleton 2 have 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 backrest frames 1 thickness and attic base skeleton 2 thickness are 2mm ~ 6mm, as 2mm, 3.15mm, 4mm or 6mm, can ensure that the seat of machine-shaping has good mechanical property.
Described attaching parts is bolt, bearing pin etc.
Described continuous glass-fiber plastic sheet material is the thermoplastic plastics such as PP, PA or PE.
