Claims20
A method of manufacturing a vehicle seat assembly, said method comprising:
- providing a cushion assembly comprising a cushion supported on a frame;
- and
- securing a non-cloth trim material over the cushion supported on the frame, the non-cloth trim material having at least one slitted region having a plurality of scored slits having an average width of less than 4.0 mm, an average length of 0.25 to 8.0 mm, and a percent open area of 2 to 25%.
A method of manufacturing a vehicle seat assembly, said method comprising:
- providing a cushion assembly;
- and
- securing a non-cloth trim material over the cushion assembly, the non-cloth trim material having at least one slitted region capable of providing a sound absorption for the seat assembly of at least 3.25 sabines at 1,250 Hz according to ASTM C423, the slitted region comprising a plurality of laser scored slits having an average width of less than 4.0 mm, an average length of 0.25 to 8 mm, and an open area of 0.10 to 30%.
A method of manufacturing a vehicle seat assembly, said method comprising:
- providing a cushion assembly comprising a cushion supported on the frame and a fibrous layer supported on the cushion, the cushion having a first sound absorption characteristic and the fibrous layer having a second sound absorption characteristic greater than the first sound absorbing characteristic;
- and
- securing a leather trim cover over the cushion, the leather trim cover comprising:
- at least one slitted region having a plurality of laser scored slits having an average width of less than 4.0 mm and an average length of 0.25 to 8.0 mm;
- and
- at least one non-slitted region adjacent the slitted region, with the non-slitted region being substantially free of slits;
- wherein the slitted region is located in an area of the trim material where noise is likely to deflect and the fibrous layer is separate from the trim material and is located between the cushion and the slitted region of the trim material.
