Preferably, described vertebral part includes multiple large projection, the equal ovalize of each large projection, and multiple large projection is spacing side by side setting successively from top to bottom, is connected with small embossment between adjacent two large projections.
Preferably, each gasket part described is protrusion, recessed and protrusion from top to bottom successively.
Preferably, each gasket part described is in the low trend in middle high outside from close mid portion to lateral direction part.
Preferably, each gasket part described is connected to form side by side by multiple dowel.
Preferably, described protuberance is yi word pattern.
Preferably, described protuberance is inverted U, and wherein remain silent towards the centre in portion of basic unit, opening toward the outer side.
Use a knapsack for aforementioned back pad, include knapsack body and aforementioned back pad, back pad is sewn on the position of back of knapsack body.
The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
The projection of this product can allow sensation during user's knapsack amplify, timely adjustment braces, knapsack position etc., lobe shape design can be fitted when knapsack user back, comfortable and alleviate and bear burden, gasket part can adapt to bending to be adjacent to user's muscle of back better, fit comfortable while, loosen muscular burden as far as possible, and bending adaptation user can be carried out from larger scope, be unlikely to not support completely and slack and undisciplined, user's knapsack burden of releiving could be realized better, this Total Product profile design can cater to action during physiological curve and the knapsack at human vertebra and back better, product comfort level is better.

Detailed description of the invention
Please refer to shown in Fig. 1 to Fig. 5, that show the concrete structure of a kind of back pad 100 of the preferred embodiment of the utility model, include back pad body 10.
This back pad body 10 is EVA resilient foam material, back pad body 10 includes portion of basic unit 11, vertebral part 12, protuberance 13 and two gasket part 14, this vertebral part 12, protuberance 13 and two gasket part 14 are all in the surface one upwards projection formation in portion of basic unit 11, each gasket part 14 is all in arc shape, in the present embodiment, it is in " ∫ " shape, two gasket part 14 are symmetricly set in the both sides of vertebral part 12 respectively, distance between two gasket part 14 is be separated from top to bottom successively, draw close the camber line trend with separate design, the distance of separating between two gasket part 14 lower ends is greater than the distance between two gasket part 14 upper ends, this protuberance 13 is between the lower end of two gasket part 14, protuberance 13 is connected with the lower end of vertebral part 12.
Specifically, in the present embodiment, this vertebral part 12 includes multiple large protruding 121, each large protruding 121 equal ovalize, and multiple large protruding 121 spacing side by side settings successively from top to bottom, are connected with small embossment 122 between adjacent two large protruding 121.This protuberance 13 is in yi word pattern, and certainly, this protuberance 13 can be also inverted U, and wherein remain silent towards the centre in portion of basic unit 11, opening toward the outer side.This each gasket part 14 is protrusion, recessed and protrusion from top to bottom successively, and this each gasket part 14 is from being be trend low outside middle height to lateral direction part near mid portion, and this each gasket part 14 is connected to form side by side by multiple dowel 141.
And the periphery of this back pad body 10 is provided with ribbon 20, the surface coverage of this back pad body 10 has individual layer screen cloth or Lycra cloth 30, to realize better air permeable effect.
Please refer to shown in Fig. 6, that show the concrete structure of a kind of knapsack of the preferred embodiment of the utility model, include knapsack body 40 and back pad 100, back pad 100 is sewn on the position of back of knapsack body 40.
This product is in result of use, vertebral part 12 is with reference to human body spinal shape, be designed to some ellipses large protruding 121 from top to bottom distribute successively, be connected by small embossment 122 between each large protruding 121, projection can allow sensation during user's knapsack amplify, timely adjustment braces, knapsack position etc., lobe shape design can be fitted when knapsack user back, comfortable and alleviate and bear burden, when user's knapsack needs jackknife and form larger radian, small embossment 122 can support back pad 100 be unlikely to be formed cannot restore completely bending while, certain space is provided to jackknife with user for overall back pad 100 and bending thus keep being close to.
During knapsack, user has flexes in various degree, braces is to back pad 100 upper left simultaneously, upper right, lower-left, bottom right four direction applies pulling force, this back pad 100 is exactly design to adapt to this needs bending laminating user back, gasket part 14 is mainly adjacent to user's muscle of back, fit comfortable while, loosen muscular burden as far as possible, the design that gasket part about 14 is recessed in the middle of protruding, bending adaptation user can be carried out from larger scope, in gasket part 14, each dowel 141 can carry out trickleer bending adjustment to be adjacent to user, especially when two kinds of dowels 141 have whole height to distinguish, this bending effect is better.
Protuberance 13 adopts two kinds of designs, is also to realize above-mentioned bending effect better, and inverted U is designed with remains silent, and bendability own is relatively low, comparatively strong with location bending between yi word pattern, is realized by the collocation of bendability power.The trend design that in the middle of gasket part 141, high outside is low, one caters to the distribution of human body back muscle, when aforementioned four direction force forgotten by two braces when carrying out knapsack, back pad 100 warp tendency can be caused to be that these four points are to central point, back pad is higher to medial side, and low the remaining silent of protuberance 13 bendability of inverted U is also be positioned at this side, can make back pad 100 entirety adapt to user and bending while, be unlikely to not support completely and slack and undisciplined, user's knapsack burden of releiving could be realized better.
In sum, the profile design of the whole back pad 100 of this product, all in order to action when catering to physiological curve and the knapsack of human vertebra and back designs.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
