Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a center pillar seal which is attached to a center pillar of an automobile and seals a gap between front and rear doors in the vertical direction from the inside of the vehicle.

[0002]

2. Description of the Related Art In the drawings, M is above a vehicle,
N is the bottom, V is the front, W is the rear, X is the inside of the vehicle, and Y is the outside of the vehicle.

Conventionally, as a center pillar seal which is attached to a center pillar and seals a gap between the front and rear door sashes in the vertical direction from the inside of the vehicle, as shown in FIGS. 1 to 4, a base portion attached to the center pillar 10 is used. A seal lip 32 having a curved surface with a substantially L-shaped cross section is integrally joined to the rear end of the front end 31, and the front end portion thereof is connected to the front door sash 20.
The one that is elastically contacted with the rear end edge of the rear door sash 25 and the middle part thereof is elastically contacted with the front end edge of the rear door sash 25 is used.

Further, as shown in FIGS. 1 and 5 to 7,
A hollow seal portion 42 having a cross section having a base portion 41 as a base and having an approximately isosceles triangular shape is integrally joined to a base portion 41 attached to the center pillar 10, and front and rear end surfaces thereof are provided on both front and rear door sashes 20, 25. In addition to being elastically contacted with the vertical edges of the doors, short lips 43, 44 symmetrically projecting on both sides of the apex are elastically contacted with the inner surfaces of the vertical edges of both door sashes 20, 25. ing.

Numerals 70, 70 are weather strips that elastically contact the front and rear portions of the center pillar 10 to seal between the center pillar 10 and the door sashes 20, 25. It is attached to the step inside the vehicle through retainers 21 and 26. Also,
Arrows P and Q indicate the entrance trajectories of the front and rear door sashes 20 and 25, respectively.

However, among the above-mentioned conventional center pillar seals shown in FIGS. 2 to 4, there are variations in assembly, and as shown in FIG. 3, the front door sash 20 causes the tip portion of the seal lip 32 to stick to the vehicle. If you drive it inward and compress it to H, the middle part will be rear door sash 2
5, a gap J is generated, and conversely, as shown in FIG. 4, when the rear door sash 25 pushes the intermediate portion of the seal lip 32 into the vehicle interior and K and compresses G, the tip portion of the seal lip 32 causes the front door sash 20 to move. There is a problem in that a gap L is formed apart from the above, a seal breakage occurs, and the range in which both door sashes 20 and 25 form a complete seal becomes extremely narrow.

Further, as shown in FIGS. 5 to 7, when the front door sash 20 is displaced rearward as shown in FIG.
The front door sash 20 rides on the apex of the hollow seal portion S, and the rear door sash 25 as shown in FIG.
Is behind the short lip 44 on the rear side,
There is a problem that the short lip 44 protrudes to the outside of the rear door sash 25, and similarly, the range in which both door sashes 20 and 25 form a complete seal becomes extremely narrow.

[0008]

The problem to be solved is that the conventional center pillar seals 30 and 40 are
If there are variations, both door sashes 20, 2
5 is that the range in which a complete seal is established is extremely narrow, and the present invention provides a center pillar seal excellent in sealing property that solves the above problems.

[0009]

Means for Solving the Problems An explanation will be given with reference to FIGS. 1 and 8 to 10. The present invention is a center pillar seal that is attached to the center pillar 10 and seals a gap between the front and rear door sashes 20 and 25 in the vertical direction from the inside of the vehicle.
Rear door sash 25 Outer wall 5 that elastically contacts the inner surface of the front edge
A hollow seal portion 52 having a substantially rectangular cross section having 2a ,
The outer surface wall 52a front end is positioned between the front door sash 20 rear end edge and the rear door sash 25 front edge, the front door sash 20 trailing edge internal surface and the hollow seal portion 52 outer surface wall 52a front lip 53 where to be elastically contacted It is formed by projecting to.

Further , the rear door sash (25) has a hollow shell.
If the compression part (52) is pushed inside the vehicle,
The lip lip (53) pivots outward around the front wall,
It is good to try to move closer to the door sash
Yes. In this case, the base portion 5 of the hollow seal portion 52 may be used as necessary.
The wall thicknesses C and D of the wall portion 55 standing upright at 1 may be thinner than the wall thickness E of the lip 53.

[0011]

EXAMPLE An example of the present invention will be described. 10 is a center pillar, 20 and 25 are front door sash and rear door sash, respectively, and 50 is a center pillar 10.
It is a center pillar seal that is attached to a vehicle to seal the gap between the vertical end edges of the front and rear door sashes 20 and 25 from the inside of the vehicle, and is configured as follows.

Reference numeral 51 denotes a base portion attached to the center pillar 10, 52 denotes a hollow seal portion integrally coupled to the base portion 51 and having a substantially rectangular cross section.
It is made to elastically contact the inner surface of the front edge. Reference numeral 53 denotes a lip projecting from the hollow seal portion 52 at the front end on the vehicle outer side so as to make elastic contact with the inner surface of the rear edge of the front door sash 20. Strictly speaking, the hollow seal portion 52 is
The outer surface wall 52a is arranged so as to come between the rear end edge of the front door sash 20 and the front end edge of the rear door sash 25. Further, if the wall thicknesses C and D of the wall portion 55 standing on the base portion 51 of the hollow seal portion 52 are made thinner than the wall thickness E of the lip 53, the operation is improved.

Numerals 70 and 70 are weather strips which are elastically contacted with the front and rear parts of the center pillar 10 to seal between the center pillar 10 and the door sashes 20 and 25. It is attached to the step inside the vehicle through retainers 21 and 26. Also,
Arrows P and Q indicate the entrance trajectories of the front and rear door sashes 20 and 25, respectively.

[0014]

When the front door sash 20 and the front door sash 20 are assembled in a different manner so that the front door sash 20 pushes the lip 53 into the vehicle as shown in FIG. The hollow seal portion 52 is rotatably displaced outwardly about the front wall as an axis to approach the rear door sash 25 and make elastic contact therewith. On the contrary, as shown in FIG. 10, even if the rear door sash 25 pushes the intermediate portion of the hollow seal portion 52 toward the inside of the vehicle and compresses it, the seal lip 53 pivots outward Z around the front wall, and the front door sash 20 Since both of the door sashes 20 and 25 come into close contact with each other and are elastically contacted with each other, a complete seal is always established without causing a seal break.

[0015]

Since the present invention is constructed as described above,
Even if the front and rear door sashes 20 and 25 are assembled differently, both the door sashes 20 and 25 are elastically contacted with the lip 53 and the hollow seal portion 52, respectively, so that a complete seal is established.
