  • Patent number: 11440388
    Abstract: A vehicle door seal includes a first wall portion and a second wall portion extending from the first wall portion, the first wall portion and second wall portion combining to define a flow passage. A projection extends from an exterior surface of the second wall portion along an entire length of the second wall portion. The projection is structured to convey excess moisture from a relatively higher portion of the seal downwardly toward another, relatively lower portion of the seal for drainage.

  • Patent number: 10160494
    Abstract: A vehicle body front section structure includes a front side member, an outer side frame member, a linking member, and a reinforcing structure. The outer side frame member is disposed separated from the front side member at a vehicle width direction outer side, has a vehicle front-rear direction rear end connected to an apron section or to a front pillar, and has a vehicle front-rear direction front end side overlapping with a vehicle front-rear direction front end side of the front side member in side view. The linking member links the vehicle front-rear direction front end side of the front side member and the vehicle front-rear direction front end side of the outer side frame member, and is input with a collision load. The reinforcing structure reinforces the outer side frame member at a portion of the outer side frame member overlapping with the front side member in side view.

  • Patent number: 9796425
    Abstract: A step portion that is farther toward a vehicle width direction outside than a cabin inside vertical wall portion, is set on a door inner panel. A portion of the step portion is a first overlapping portion that is arranged in a position overlapping with an outside vertical wall portion of a center pillar in a vehicle side view. A portion of the outside vertical wall portion of the center pillar is a second overlapping portion that faces the first overlapping portion at a distance that is narrower than a distance between the step portion and the cabin inside vertical wall portion. A third overlapping portion that is connected to the first overlapping portion in a position overlapping with the second overlapping portion of the center pillar in the vehicle side view, is set on an end portion of a beltline reinforcement in a length direction thereof.

  • Patent number: 9004576
    Abstract: When a collision load is transmitted to a gusset, the load is transmitted to an inner side in a vehicle width direction via an inclined wall. Accordingly, moment that causes a front side member to be projected and bent inward to the inner side in the vehicle width direction with an intersection being a starting point acts on the front side member. Then, the front side member, which has been projected and bent inward, collides with a power unit that is disposed in an engine compartment from an outer side in the vehicle width direction. Accordingly, a lateral force to the inner side in the vehicle width direction can be obtained for a vehicle.

  • Patent number: 5902104
    Abstract: An orthodontic wire supporting device, for example, in the form of a bracket improved so that the bracket can be reliably held on teeth during a period of orthodontic treatment but easily detached from teeth, if it is desired, for exchange of the bracket with a fresh one. A base of the bracket destined to be bonded to the tooth plane by means of an adhesive layer is formed adjacent four corners with anchoring holes each defined by a truncated cone having its diameter on the upper side smaller than its diameter on the lower side of the base. The lower side of the base is coated with the adhesive layer, and then the base is pressed against the tooth plane with an appropriate force so that the adhesive layer is partially forced to pass through the respective anchoring holes and to project from the upper side of the base.
