Abstract
A web adjuster for securing a web and a seat including the web adjuster. The web extends through the web adjuster including a mounting plate that is mounted to the seat. A sliding plate moves relative to the mounting plate for lockingly engaging the web. Resilient biasing elements bias the sliding plate into locking engagement, and a release handle displaces the sliding plate against the resilient biasing elements.
Claims12
An adjuster for limiting longitudinal movement of an elongated web with respect to a base, the adjuster comprising:
- a mounting plate adapted to be fixed to the base, the mounting plate including:
- a first major face generally lying in a first plane;
- a second major face generally lying in a second plane parallel to the first plane, the second plane being spaced from the first plane by a first distance equal to a thickness of the mounting plate;
- a first bridge rising a second distance above the second major face;
- and
- a first aperture penetrating through the mounting plate, the first aperture defining a first edge extending from the first major face to the second major face;
- a sliding plate displaceable in shear with respect to the mounting plate, the sliding plate including:
- a first major surface generally lying in a third plane that is parallel to the first place, the first major surface confronting and slidingly engaging the second major face;
- a second major surface generally lying in a fourth plane that is parallel to and spaced from the third plane by a third distance equal to a thickness of the sliding plate;
- a second aperture penetrating through the sliding plate from the first major surface to the second major surface;
- and
- at least one finger retaining the sliding plate with respect to the mounting plate, each at least one finger confronting and slidingly engaging the first major face of the mounting plate;
- and
- a plateau rising a fourth distance above the first major surface;
- a neck extending transversely under the first bridge;
- and
- at least one resilient element biasing the plateau toward the first edge in a first shear direction.

A seat for holding a child, the seat comprising:
- a seat portion and a back portion integrally connected to the seat portion;
- a harness adapted for securing the child with respect to the seat, the harness including shoulder straps extending from a front side of the back portion to a rear side of the back portion, the shoulder straps being adapted to overlie shoulders of the child;
- a web slidably connected to the harness on the rear side of the back portion;
- and
- an adjuster engaging the web, the adjuster comprising:
- a mounting plate adapted to be fixed to the base, the mounting plate including:
- a first major face generally lying in a first plane;
- a second major face generally lying in a second plane parallel to the first plane, the second plane being spaced from the first plane by a first distance equal to a thickness of the mounting plate;
- a first bridge rising a second distance above the second major face;
- and
- a first aperture penetrating through the mounting plate, the first aperture defining a first edge extending from the first major face to the second major face;
- a sliding plate displaceable in shear with respect to the mounting plate, the sliding plate including:
- a first major surface generally lying in a third plane that is parallel to the first place, the first major surface confronting and slidingly engaging the second major face;
- a second major surface generally lying in a fourth plane that is parallel to and spaced from the third plane by a third distance equal to a thickness of the sliding plate;
- a second aperture penetrating through the sliding plate from the first major surface to the second major surface;
- and
- at least one finger retaining the sliding plate with respect to the mounting plate, each at least one finger confronting and slidingly engaging the first major face of the mounting plate;
- and
- a plateau rising a fourth distance above the first major surface;
- a neck extending transversely under the first bridge;
- and
- at least one resilient element biasing the plateau toward the first edge.
