Sealing assembly for an electrophotographic image forming device
A sealing assembly according to one example embodiment includes a housing and an imaging component positioned on the housing. A seal has opposed first and second edges extending along a longitudinal dimension of the seal. A lateral dimension of the seal is perpendicular to the longitudinal dimension and extends in a direction from the first edge to the second edge. The seal is attached to the housing along the first edge and contacts the imaging component along the second edge. Upon attachment to the housing, the seal is elastically deformed from an unassembled state in which the second edge has a first profile that varies in the lateral dimension along the longitudinal dimension to an assembled state in which the second edge is deformed relative to the first profile to a second profile having less variation in the lateral dimension along the longitudinal dimension than the first profile.
1. A sealing assembly for use in an electrophotographic image forming device, comprising:
a housing;
an imaging component positioned on the housing; and
a seal having opposed first and second edges extending along a longitudinal dimension of the seal, a lateral dimension of the seal is perpendicular to the longitudinal dimension and extends in a direction from the first edge to the second edge, the seal is attached to the housing along the first edge and contacts the imaging component along the second edge, wherein upon attachment to the housing the seal is elastically deformed from an unassembled state in which the second edge has a first profile that varies in the lateral dimension along the longitudinal dimension to an assembled state in which the second edge is deformed relative to the first profile to a second profile having less variation in the lateral dimension along the longitudinal dimension than the first profile.
2. The sealing assembly of claim 1 , wherein in the unassembled state of the seal the second edge of the seal tapers toward the first edge from first and second end portions of the second edge toward a central portion of the second edge.
3. The sealing assembly of claim 2 , wherein in the unassembled state of the seal the second edge of the seal tapers linearly toward the first edge from the first and second end portions of the second edge toward the central portion of the second edge.
4. The sealing assembly of claim 2 , wherein in the unassembled state of the seal the second edge of the seal curves toward the first edge from the first and second end portions of the second edge toward the central portion of the second edge.
5. The sealing assembly of claim 1 , wherein in the assembled state of the seal the second edge of the seal extends uniformly in the lateral dimension along the longitudinal dimension.
6. The sealing assembly of claim 1 , wherein in the unassembled state of the seal the first edge of the seal extends uniformly in the lateral dimension along the longitudinal dimension.
7. The sealing assembly of claim 1 , wherein in the unassembled state of the seal the first edge of the seal varies in the lateral dimension along the longitudinal dimension.
8. The sealing assembly of claim 1 , wherein the first edge of the seal includes a notch formed at a middle section of the first edge for receiving a reference datum during assembly of the seal onto the housing.
