  • the trim cover 22 can be any material known in the art, including but not limited to, vinyl and cloth.
  • the seat core 24 may be made of any core material known in the art, such as a foam core, and may be made of any number of known materials including, but not limited to, polypropylene, polyurethane, expanded polypropylene, or polyethylene.
  • a trim cover retainer assembly 20, as shown in Figure 3, is used to join at least two edges 26, 28 of the trim cover 22 to the core 24.
  • the trim cover retainer assembly 20 runs longitudinally along any point in the vehicular component requiring the mating of the trim cover 22 to the core 24.
  • the trim cover retainer assembly 20 may be used in connection with any portion of the seating assembly or seating components including, for example, the head restraint, seat base or seatback.
  • Figure 4 shows a head restraint with the trim cover 22 fixed to the seat core 24 with the trim cover retainer assembly 20.
  • the trim cover retainer assembly 20 includes a first retainer 30 and a second retainer 32.
  • the first retainer 30 is attached to a first edge 26 of the trim cover 22 and the second retainer 32 is attached to a second edge 28 of the trim cover 22.
  • retainers 30, 32 are sewn onto the trim cover 22 but it should be appreciated that many other methods may be used to attach the retainers 30, 32 to the trim covers 22, including but not limited to, glue, adhesives, tapes, and material welding.
  • the first retainer 30 is partially U-shaped and includes at least one external barb 34 and at least one internal barb 36 to fixedly attach first retainer 30 to core 24.
  • the first retainer 30 may include a plurality of external barbs 34.
  • the first retainer 30 includes two external barbs 34 that extend in opposite directions to engage the core 24.
  • Second retainer 32 includes at least one retention barb 38 interfacing with internal barb 36 of first retainer 30 to position and fix second retainer 32 inside of first retainer 30 after complete insertion and installation of second retainer 32 into first retainer 30.
  • Retainers 30, 32 may be made of any material including for example, extruded polypropylene.
  • the core 24 is provided with a core cavity 40 for receiving the trim cover retainer assembly 20.
  • core cavity 40 may be formed in many ways including, without limitation, by molding the core cavity 40 into the core 24 when the core 24 is formed.
  • the core cavity 40 may be many different sizes and shapes so long as a portion of the core cavity 40 is narrower than the overall width of first retainer 30.
  • the core cavity 40 shape is deformed around at least a portion of first retainer 30.
  • Second retainer 32 includes a first end 42 for attaching to the trim cover 22, a second end 44 having a retention barb 38 formed thereon and a second indicator 46 formed between the first and second ends 42, 44.
  • Second indicator 46 is provided as a visual locator when attaching the trim cover 22 to the second retainer 32.
  • the second edge 28 of the trim cover 22 is aligned with reference to second indicator 46 to ensure the appropriate amount of material is used in connecting the trim cover 22 to second retainer 32.
  • the second indicator 46 is a ridge extending outwardly from an internal surface of the second retainer 32.
  • second indicator 46 can be provided in many other shapes or sizes so long as the trim cover 22 can be appropriately positioned and attached to second retainer 32.
  • Retention barb 38 is shown extending in a direction toward first end 42 of second retainer 32 such as in the form of a partial arrow, however, it should be appreciated that other shapes may be used for retention barb 38 so long as retention barb 38 interfaces with internal barb 36 of first retainer 30 to provide the desired retention of second retainer 32 to first retainer 30.
  • First retainer 30, as shown in Figure 7, is partially U-shaped including a first retainer base 48 for attaching to the core 24, a first leg 50 extending in a direction toward the trim cover 22 and a second leg 52 extending in a direction toward the trim cover 22.
  • First leg 50 and second leg 52 define a retainer cavity 54 for receiving second retainer 32 when inserted into first retainer 30.
  • first leg 50 is shorter than the length of second leg 52 to provide for ease of insertion of second retainer 32 into retainer cavity 54. It should be appreciated that the amount of difference in the length of the first leg 50 to the second leg 52 depends on many design factors including, among others, the amount of trim cover 22 material attached to each of the retainers 30, 32, and the amount of interface between the retention barb 38 and the internal barb 36.
  • the first retainer base 48 of the first retainer 30 is shaped for reduced resistance when inserted into the core cavity 40 of the core 24 and, in this embodiment, is shown shaped like the head of an arrow as shown in Figures 7 and 8.
  • the first retainer base 48 includes the at least one external barb 34.
  • two external barbs 34 are disposed on the first end 42.
  • the external barbs 34 are disposed on opposite ends of the first retainer base 48 and extend outwardly from the first retainer base 48 of the first retainer 30 toward the trim cover 22.
  • the second leg 52 of first retainer 30 includes the internal barb 36 that extends in a lateral direction toward the first leg 50, and a first indicator 56.
  • the location of internal barb 36 on the second leg 52 is important since it has been found that second retainer 32 may try to pivot out of first retainer 30, however, the placement of internal barb 36 on the second leg 52 helps to prevent or limit second retainer 32 from pivoting out of first retainer 30.
  • Both first indicator 56 and internal barb 36 extend along the length of first retainer 30.
  • first indicator 56 is provided as a visual locator when attaching the trim cover 22 to first retainer 30.
  • first edge 26 of the trim cover 22 is aligned with reference to first indicator 56 to ensure the appropriate amount of material is used in connecting the trim cover 22 to first retainer 30.
  • the first indicator 56 is a groove extending inwardly into the second leg 52 of the first retainer 30. It should be appreciated that, like second indicator 46 of second retainer 32, first indicator 56 can be provided in many other shapes or sizes so long as the trim cover 22 can be appropriately positioned and attached to first retainer 30. [0030] As shown best in Figure 8, the spacing of retainer cavity 54 of first retainer 30 at a tip of internal barb 36 is less than a maximum width of second retainer 32 at a tip of retention barb 38.
  • Figures 9 and 10 are used to detail a first method of using the trim cover retainer assembly 20.
  • first edge 26 of the trim cover 22 material is aligned with a visual indicator formed on first retainer 30, such as first indicator 56 shown in Figure 7.
  • first retainer 30 A second edge 28 of the trim cover 22 material is aligned with a visual indicator formed on second retainer 32, such as second indicator 46 shown in Figure 6.
  • second retainer 32 A second edge 28 of the trim cover 22 material is aligned with a visual indicator formed on second retainer 32, such as second indicator 46 shown in Figure 6.
  • the trim cover 22 is attached to second retainer 32.
  • First retainer 30, with the trim cover 22 attached thereto is then inserted into the core cavity 40 formed in the core 24 such that upon complete insertion the external barbs 34 deform the core 24 to fixedly attach first retainer 30 to such core 24.
  • Second retainer 32 With the trim cover 22 attached thereto, is then inserted into the core cavity 40 formed in the core 24. Second retainer 32 is further inserted into the retainer cavity 54 of first retainer 30 such that second retainer 32 is fixedly attached to first retainer 30 by the interface between retention barb 38 and internal barb 36.
  • Figure 11 is used to detail a second method of using the trim cover retainer assembly 20.
  • first edge 26 of the trim cover 22 material is aligned with a visual indicator formed on first retainer 30, such as first indicator 56 shown in Figure 7.
  • first retainer 30 After such alignment, the trim cover 22 is attached to first retainer 30.
