<p>A weatherstrip comprises an attachment portion <B>6</B> for mounting on a flange <B>5</B> of a vehicle door aperture and hollow sealing portions <B>14</B>, <B>15</B> protruding from the attachment portion <B>6</B>. The hollow sealing portions <B>14</B>, <B>15</B> comprise a first hollow sealing portion <B>14</B> mounted on the attachment portion <B>6</B> and a second hollow sealing portion <B>15</B> mounted on the first sealing portion <B>14</B>. The first sealing portion <B>14</B> comprises first <B>14a</B> and third <B>14d</B> walls projecting diagonally away from each other from a first side of the attachment portion <B>6</B> towards opposite ends of the flange <B>5</B>, second <B>14c</B> and fourth <B>14f</B> walls projecting from the first <B>14a</B> and third <B>14d</B> walls respectively back towards each other and a fifth wall <B>14g</B> connecting the second <B>14f</B> and fourth <B>14d</B> walls. With the attachment portion <B>6</B> forming a sixth wall the first hollow sealing portion <B>14</B> is hexagonal in cross section. Bending points <B>14b</B>, <B>14e</B> are provided between the first <B>14a</B> and second <B>14c</B> walls and between the third <B>14d</B> and fourth walls <B>14f</B>. The second hollow sealing portion <B>15</B> is formed by a curved wall connected to the linkage <B>14h</B> between the second <B>14c</B> and fifth <B>14g</B> walls and the linkage <B>14i</B> between the fourth <B>14d</B> and fifth <B>14g</B> walls of the first hollow portion <B>14</B>. The junction between the first <B>14</B> and second <B>15</B> hollow portions on the side which contacts the vehicle door in use is formed as a smooth continuous surface.</p> |
