Utility model content

Yet when passenger is seated at seat, generally the pars intermedia from waist to the back of the body is connected to back of seat, but the top of the back of the body is that scapula periphery is not connected to back of seat mostly.Therefore, in the situation that passenger makes scapula periphery be connected to back of seat once in a while, the areal of support shape of patent documentation 1 is brought into play its function, but under the common posture of taking one's seat, the areal of support shape of patent documentation 1 can not play a role.Therefore, the areal of support shape of patent documentation 1 is not corresponding with passenger's the common posture of taking one's seat, and its effect reduces by half.

In addition, when the top of passenger's the back of the body is connected to back of seat, mainly that spine portion between two scapulas is connected to areal of support, but in patent documentation 1, with spine portion between this scapula over against areal of support position also equally with other areal of support position by molded gasket, defined.Therefore, even if can reduce or eliminate the constriction to two scapula parts, also can cause the constriction of spine portion to raise, with regard to riding, with regard to comfort level, still leave problem.And, and between this two scapula over against areal of support position in plane as in the past (both not outstanding also not depression), so can not be poor with passenger's physique corresponding.

Therefore, it is a kind of vehicle seat used that the purpose of this utility model is to provide, and its constriction to two scapulas parts is few, and areal of support and passenger common take one's seat posture and physique poor corresponding and fit in the spine portion between scapula.

The utility model is a kind of vehicle seat used, comprise back of seat, this back of seat possess supporting passenger the upper part of the body areal of support and with the continuous side back-rest in two sides of this areal of support, described vehicle seat used being characterised in that, the Width central upper of the areal of support of described back of seat and and passenger's scapula between spine portion over against areal of support position, be provided with than other areal of support position to the side-prominent protrusion of vehicle front.

So, by make and scapula between spine portion over against areal of support position be the protrusion more outstanding than other areal of support position, even if passenger is the common posture of taking one's seat, also can make this protrusion be connected to the spine portion between scapula and support.On the other hand, by with two scapulas parts over against areal of support position in plane as in the past (not caving in as patent documentation 1), result is to move back to rear view of vehicle rear flank than protrusion.Thus, can reduce or eliminate the constriction to two scapulas.Thereby, can improve passenger's comfort level by bus.

And under the common posture of taking one's seat (vehicle driving posture), protrusion is in being embedded in the state between two scapulas.Accordingly, in the situation that the force of inertia (hereinafter referred to as horizontal G) of the left and right directions such as the turning during because of vehicular drive or left and right turning acts on passenger, passenger's health is not only supported from left and right directions by side back-rest, and supported from left and right central portion by protrusion, so improve with respect to the sense of stability of horizontal G.With respect to this, seat in the past certainly needless to say, even if the seat of patent documentation 1 can not obtain the sense of stability with respect to horizontal G as the utility model.

In addition, described back of seat possesses as the molded gasket that defines the padded coaming of described areal of support and side back-rest.On this basis, at described protrusion, preferably the slab liner than described molded gasket softness is disposed to the front surface of described molded gasket.

Accordingly, can alleviate the constriction to the spine portion between two scapulas, further improve comfort level by bus.And although according to passenger's physique or the posture of taking one's seat, also different to the butt pressure of protrusion, according to the butt pressure from this passenger, slab liner is flexibly out of shape.Thus, allow the poor and difference of posture of taking one's seat of passenger's physique, and can make protrusion fit in definitely the spine portion between two scapulas.

And, in the both sides of described protrusion and with passenger's two scapulas parts over against areal of support position, also preferably the slab liner than described molded gasket softness is disposed to the front surface of described molded gasket.Accordingly, in the situation that two scapulas are partly connected to areal of support while being strongly dependent on the situation of back of seat or vehicle collision etc., can relax constriction and impact to this two scapulas part.In addition, in this case, the both sides of protrusion are also in the identical plane in areal of support position with other.

Utility model effect

According to of the present utility model vehicle seat used, constriction to two scapula parts is few, and can and take one's seat posture and the poor areal of support that makes accordingly of physique of passenger common fit in definitely the spine portion between scapula, thereby can improve with respect to the sense of stability of horizontal G and comfort level by bus.
