Abstract

Abstract Body side molding for automotive vehicles comprising a plastic body formed with at least one broad channel which communicates with the bottom of the molding to enable its bottom surface to conform to curved surfaces without distorting the top of the molding. This permits the molding to be permanently adhered to the variety of contours presented by automotive vehicles.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 224 words
Body side molding of essentially uniform cross-section comprising a tough, resilient plastic body and having at least two relatively flat surfaces for receiving an adhesive to attach the molding to the side of a vehicle, which adhesive-receiving surfaces extend across most of the width of the molding substantially to each of its sidewise extremities, other surfaces of the molding providing a tough, durable scuff- and weather-resistant, impact-absorbing and esthetically pleasing exterior, characterized by the features that a. the plastic body is formed to have a trunk and two ankles, each defining one sidewise extremity of the molding and terminating in a foot which supports at least part of one of said adhesive-receiving surfaces, b. the total ankle thickness is less than 50% of the overall width of the plastic body, c. there is a channel at the underside of the trunk and at least one groove formed in the trunk adjacent the channel such that the thickness of the trunk at the groove is less than one-half the average thickness of the trunk at said channel, and d. the average thickness of each foot portion of the plastic body which protrudes laterally beyond an ankle is less than 1/3 of the overall height of the molding, which features enable the adhesive-receiving surfaces to conform to curved substrates without distorting the top of the molding.
Claim 2
Dependent Claim 224 words
Body side molding of essentially uniform cross-section comprising a tough, resilient plastic body and having at least two relatively flat surfaces for receiving an adhesive to attach the molding to the side of a vehicle, which adhesive-receiving surfaces extend across most of the width of the molding substantially to each of its sidewise extremities, other surfaces of the molding providing a tough, durable scuff- and weather-resistant, impact-absorbing and esthetically pleasing exterior, characterized by the features that a. the plastic body is formed to have a trunk and two ankles, each defining one sidewise extremity of the molding and terminating in a foot which supports at least part of one of said adhesive-receiving surfaces, b. the total ankle thickness is less than 50% of the overall width of the plastic body, c. there is a channel at the underside of the trunk and at least one groove formed in the trunk adjacent the channel such that the thickness of the trunk at the groove is less than one-half the average thickness of the trunk at said channel, and d. the average thickness of each foot portion of the plastic body which protrudes laterally beyond an ankle is less than 1/3 of the overall height of the molding, which features enable the adhesive-receiving surfaces to conform to curved substrates without distorting the top of the molding.
Claim 3
Dependent Claim 45 words
Body side molding as defined in claim 1 further characterized by the feature that at least one channel at the underside of the trunk is at least partially filled with a soft, compliant foam which does not substantially interfere with the conformability of the molding.
Claim 4
Dependent Claim 27 words
Body side molding as defined in claim 2 further characterized by the feature that said foot and foam abut and together provide said relatively flat adhesive-receiving surface.
Claim 5
Dependent Claim 23 words
Body side molding as defined in claim 1 further characterized by the feature that an adhesive layer is adhered to each adhesive-receiving surface.
Claim 6
Dependent Claim 31 words
Body side molding as defined in claim 4 further characterized by the feature that each adhesive layer is a pressure-sensitive adhesive layer and is normally protected by a disposable low-adhesion liner.
Claim 7
Dependent Claim 29 words
Body side molding as defined in claim 1 further characterized by the feature that there is at least one decorative foil adhered to the exterior of the plastic body.
Claim 8
Dependent Claim 49 words
Body side molding as defined in claim 6 further characterized by the feature that the decorative foil extends around the ankles at the sidewise extremities and across the foot of each such ankle, and an adhesive layer is adhered to the face of the decorative foil opposite the foot.
Claim 9
Dependent Claim 36 words
Body side molding as defined in claim 1 further characterized by the feature that said plastic body has a C-shaped cross-section and a foot at each end of the C protruding laterally toward the other foot.
Claim 10
Dependent Claim 37 words
Body side molding as defined in claim 8 further characterized by the feature that the adhesive-receiving surfaces are normally planar and the plane of one deviates from the plane of the other by an angle of 5°-45°.
Claim 11
Dependent Claim 34 words
Body side molding as defined in claim 8 further characterized by the feature that the two feet nearly touch each other to provide adhesive-receiving surfaces which are nearly the full width of the molding.
Claim 12
Dependent Claim 21 words
Body side molding as defined in claim 5 further characterized by the feature that the adhesive layer includes a cushioning foam.
Claim 13
Dependent Claim 177 words
Body side molding of essentially uniform cross-section comprising a tough, resilient plastic body and having at least one relatively flat surface for receiving an adhesive to attach the molding to the side of a vehicle, other surfaces of the molding providing a tough, durable scuff- and weather-resistant, impact-absorbing and esthetically pleasing exterior, characterized by the feature that a. the plastic body is formed to have a trunk and at least one ankle terminating in a foot which supports at least part of said adhesive-receiving surface, b. the total ankle thickness is less than 50% of the overall width of the plastic body, c. the average thickness of any and all foot portions of the plastic body which protrude beyond an ankle is less than 1/3 of the overall height of the molding, and d. said plastic body is formed in two parts, each having a foot, an ankle and a trunk portion which is joined to the other trunk portion by a tough, flexible foil to provide a single molding having a hinging action at the foil.
