Promptly, first aspect present invention is characterised in that in the motor bike of the upper surface that is covered in the cushion material that overlaps on the seat bottom plate with skin-material, in described seat, the amount of compression of the cushion material of the buttocks position of direct contact passenger buttocks is set at greater than the amount of compression that does not contact the buttocks part.
By set the hardness of cushion material self in advance than the lowland, increase the amount of compression of cushion material in the buttocks position and form high density, can set the hardness of this part with the size that is suitable for using beginning period in the seat.Therefore, can guarantee that the seat uses the taking of seat of the buttocks position in beginning period to feel good.
After generation elastic force weakens phenomenon in the cushion material in the buttocks position, use beginning to compare period, reduced the hardness of the cushion material self in the buttocks position with the seat.
But with original the same,, weaken phenomenon, also do not have too big difference even therefore produce elastic force because the hardness ratio of cushion material self is less.Yet, owing to realized high density by the amount of compression of setting the cushion material significantly, even take the sensation maintenance well so that after generation elastic force weakens phenomenon, also can make,, also can fully guarantee the hardness of cushion material in the buttocks position even therefore having produced elastic force weakens phenomenon.As a result, can guarantee that taking of seat felt good in the buttocks position after elastic force weakens phenomenon and takes place.
Like this, can guarantee that taking of seat felt good in the buttocks position.
In second aspect present invention, it is characterized in that, upper surface at seat bottom plate is provided with a plurality of auxiliary strengthening ribs, the cushion material forms lower surface with basic aspect, simultaneously, part at a plurality of auxiliary strengthening ribs of correspondence forms the auxiliary enterable recess of strengthening rib, in described a plurality of recesses, makes the recess at position, corresponding described buttocks position more shallow than the recess of not corresponding buttocks position.
Because the recess at the position of corresponding buttocks position is superficial,, also can fully permeate in the part between the recess at expanded material position, aforementioned buttocks position in being equivalent to die cavity even therefore in the die cavity of metal paattern, do not inject a large amount of expanded materials.Therefore, when forming the shape of cushion material lower surface, can guarantee the thickness of cushion material with desired shape, owing to reduced Master Cost by the consumption that reduces expanded material, therefore can reduce the price of cushion material, the result has realized the reduction of seat cost.

The invention is characterized in: at a plurality of recess 92H ..., 92A ... in, the recess at the position of corresponding buttocks position HP1 is (hereinafter referred to as [buttocks position recess 92H ... ]) compare the recess of not corresponding buttocks position HP1 (hereinafter referred to as [other recess 92A ... ]) more shallow.To this, will describe in detail among Fig. 8 below.
Fig. 8 (a)-(c) is for relating to the scheme drawing at seat of the present invention.
(a) be depicted as the preceding seat 19 of assembling.From the outstanding auxiliary strengthening rib 84 of seat bottom plate 80 ... height be H1.On the other hand, the thickness of cushion material 90 is T1, the buttocks position recess 92H in cushion material 90 ... the degree of depth be D1, other recess 92A ... the degree of depth be D2.
With respect to auxiliary strengthening rib 84 ... height H 1, other recess 92A ... depth D 2 roughly the same, other recess 92A relatively ... depth D 2, with buttocks position recess 92H ... depth D 1 to set ground less.That is the depth D 1 of buttocks position recess 92H ... than other recess 92A ... depth D 2 shallow, simultaneously, less than the height H 1 of auxiliary strengthening rib.
The ideal dimensions of the depth D 1 of buttocks position recess 92H is equivalent to the 5-20% of cushion material thickness T1, the better 10%-15% that is equivalent to cushion material thickness T1 that is of a size of.
(b) shown when overlapping cushion material 90 on the seat bottom plate 80, covered the state of the upper surface of described cushion material 90 with skin-material 100.
By this state, assemble by the cushion material 90 that contracts to seat bottom plate 80 side pressures and can make seat 19.
In the HP1 of buttocks position, the power P1 (compressive force P1) of compression cushion material 90 is greater than the power P2 (compressive force P2) of compression cushion material 90 among the secondary buttocks position HP2, in addition, compressive force P2 is greater than the power P3 (compressive force P3) of compression cushion material 90 in the contact buttocks.The relation that promptly has P1＞P2＞P3, these compressive forces P1-P3 is distributed load.Shown this result in below (c).
(c) shown finished product seat 19,, the amount of compression C1 of the cushion material 90 among the HP1 of buttocks position has been set at amount of compression C2 greater than contact buttocks part (C1＞C2) by setting compressive force P1-P3 as described in above-mentioned (b).Therefore, after being compressed, in the thickness T 2 of the cushion material 90 of buttocks position HP1 less than the thickness T 3 of contact buttocks part (T2＜T3).In this part, the density of the cushion material 90 among the HP1 of buttocks position is higher.
Therefore, the amount of compression C1 of the cushion material 90 by increasing buttocks position HP1 realizes high density, can improve the hardness of the cushion material 90 among the HP1 of buttocks position.
In general, owing to only adopted cheap material as cushion material 90, therefore the hardness ratio initial stage hardness of cushion material 90 reduces to some extent in long-term use, thereby has produced the phenomenon that cushion material 90 antagonistic forces reduce, i.e. " elastic force weakens phenomenon ".As a result, taking of seat 19 feels not good.So-called " elastic force weakens phenomenon " is the phenomenon that the hardness of cushion material 90 reduces.
Yet, if taking the hardness that sensation is set cushion material 90 after cooperating elastic force to weaken, can cause using seat 19 hardness in beginning period too high, it is excessively hard promptly to form what is called.Even set hardness and feel good, then can cause using beginning period excessively hard and make and take sensation and worsen to weaken at elastic force to make to take after phenomenon produces than the highland.
, seat 19 is by being covered in the upper surface of the cushion material 90 that overlaps on the seat bottom plate 80 with skin-material 100, and assembles manufacturing to the seat bottom plate 80 side pressures cushion material 90 that contracts.Set the hardness S1 of cushion material 90 self in advance than the lowland, in manufacturing process,, can improve the density of cushion material 90 by setting the amount of compression C1 of cushion material 90 significantly.Like this, by forming high density, use the suitable size in beginning period to set the hardness of cushion material 90 with the seat.Therefore, can guarantee the seat use beginning period seat 19 take sensation.
Yet, be cumbersome owing to increase the reduced overall amount of cushion material 90, therefore increased man-hour.Because in cushion material 90, the frequent compressive force of accepting greater than other parts of the buttocks position HP1 of direct contact passenger buttocks particularly, weaken the tendency that phenomenon produces thereby increased elastic force.
Therefore, the invention is characterized in that (1) preestablishes the hardness S1 of cushion material 90 self, (2) to form high density, interim suitable size was set the hardness S2 of the part of buttocks position HP1 to the amount of compression C1 that sets cushion material 90 among the buttocks position HP1 when (3) used beginning with the seat greater than the amount of compression C2 of contact buttocks part.
That is, emphasis is guaranteed the sensation of taking at seat 19 among the HP1 of buttocks position.Owing to increased the amount of compression C1 of the part of buttocks position HP1 in the cushion material 90, therefore be easy to compression, and can keep manufacturing cost in the past.
Herein, " the low cushion material of setting 90 self hardness S1 " in advance is than " only setting, use at the seat hardness S2 of part of the buttocks position HP1 in beginning period with amount of compression C1 compression cushion material 90 " little (S1＜S2).
In sum, set the hardness S1 of cushion material 90 self in advance than the lowland, the amount of compression C1 that increases cushion material 90 among the buttocks position HP1 to be forming high density, can set the hardness S2 of its part with the size that the seat use beginning to be fit to period.Therefore, can guarantee that the seat uses the taking of seat 19 of the buttocks position HP1 in beginning period to feel good.
After in the cushion material 90 of buttocks position HP1, having produced elastic force and weakening phenomenon, use beginning to compare period, reduced the hardness of cushion material among the HP1 of buttocks position 90 self with the seat.
Yet with original the same, the hardness S1 of cushion material 90 self is smaller, does not also have too big difference even generation elastic force weakens phenomenon.Promptly can weaken the reduced rate (improve durability and worsen level) of cushion material 90 hardness.
And even can be good to take sensation after weakening phenomenon at generation elastic force owing to form high density by the amount of compression C1 that sets cushion material 90 significantly, even therefore having produced elastic force weakens phenomenon, hardness have significant difference yet yet.Therefore, fully guaranteed the hardness of cushion material 90 among the HP1 of buttocks position.As a result, can guarantee the buttocks position HP1 after elastic force weakens phenomenon and produces seat 19 take sensation.
Therefore, can guarantee the sensation of taking at seat 19 for a long time.
; in general; the expanded material injection molding is being formed under the situation of cushion material 90 after with metal paattern; if recess 92H ..., 92A ... darker, the part between the recess in being equivalent to the die cavity of forming metal mould then; expanded material is difficult to permeate very much; as a result, in the lower surface 91 of cushion material 90, the surface portion between recess is compared with inside and more is difficult to foaming.If the foaming of surface portion is incomplete, then the result who is produced is the shape that can not form lower surface 91 with desired shape, simultaneously, can not guarantee the thickness of material 90.
Foaming to guarantee recess 92H ..., 92A ... between surface portion shape complete the time, be preferably in and inject a large amount of expanded materials in the die cavity.But,, therefore be unfavorable for promoting cost to reduce owing to used a large amount of expanded materials.
And according to the foam characteristics of expanded material, because a large amount of expanded material concentrates on the surface portion of cushion material 90, so the density of surface portion is higher than inside.At recess 92H ..., 92A ... when dark, only this part has increased the skin area of high density surface part.As a result, increased the weight of cushion material 90.
To this, the present invention is being formed at the recess 92H of cushion material 90 ..., 92A ... in, should reduce buttocks position recess 92H at least ... depth D 1.
Because buttocks position recess 92H ... more shallow, even therefore do not inject a large amount of expanded materials in die cavity, expanded material is being equivalent to die cavity center dant 92H ... between part also can fully permeate.So, when forming the shape of lower surface 91, can guarantee the thickness of cushion material 90 with desired shape, owing to reduced Master Cost by the consumption that reduces expanded material, therefore reduced the price of cushion material 90, the result can realize that the cost at seat 19 reduces.
According to the present invention, buttocks position recess 92H only ... more shallow part has reduced to form the highdensity face area of cushion material 90.Therefore, only reduced the weight of cushion material 90 in this part.And, under the situation of face shaping that can not change seat 19 and thickness, can guarantee that taking of seat 19 feel good.
In the embodiment of the invention described above, motor bike 10 is not limited to motor scooter.
The present invention has brought into play following effect by above structure.
In first aspect present invention, because the amount of compression of the cushion material in the buttocks position of direct contact passenger buttocks is set at greater than the amount of compression that does not contact the buttocks part, even therefore adopting under the situation of cheap material as the cushion material, set the hardness of cushion material self in advance than the lowland, form high density by the amount of compression that increases the cushion material in the buttocks position, can set the hardness of this part with the size that is suitable for using beginning period in the seat.Therefore, can guarantee to use at the seat beginning period, taking of the seat of buttocks position felt good.
On the other hand, after in the cushion material of buttocks position, having produced elastic force and weakening phenomenon, use beginning to compare period, can reduce in the hardness of the cushion material self of buttocks position with the seat.
But with original the same,, weaken phenomenon, also do not have too big difference even therefore produce elastic force because the hardness ratio of cushion material self is less.That is, can reduce the rate of descent (improve durability and worsen level) of cushion material hardness.And, owing to realized high density by the amount of compression of setting the cushion material significantly, even feel good so that after generation elastic force weakens phenomenon, make to take,, also can fully guarantee the hardness of cushion material in the buttocks position even therefore having produced elastic force weakens phenomenon.As a result, can guarantee that taking of seat felt good in the buttocks position.
Like this, by guaranteeing the hardness of cushion material in the buttocks position, can guarantee for a long time that taking of seat feel good.And,, can reduce the cost at seat by adopting cheap material as the cushion material.
In second aspect present invention, owing to be provided with a plurality of auxiliary strengthening ribs and form the lower surface of cushion material with the general plane shape at the upper surface of seat bottom plate, simultaneously, part at a plurality of auxiliary strengthening ribs of the described lower surface of correspondence forms the auxiliary enterable recess of strengthening rib, in described a plurality of recesses, make the recess at position, corresponding buttocks position more shallow than the recess of not corresponding buttocks position, even therefore do not inject a large amount of expanded materials in the die cavity of metal paattern, the part between the recess at expanded material position, aforementioned buttocks position in being equivalent to corresponding die cavity also can fully be permeated.
Therefore, when forming the shape of cushion material lower surface, can guarantee the thickness of cushion material with desired shape.And, owing to reduced Master Cost, therefore can reduce the price of cushion material by the consumption that reduces expanded material, the result can further promote the cost at seat to reduce.
