Door trim panel with dual density bolster armrest and integrated components
View Patent ↗A door trim panel including a cover stock, an armrest coupled to the cover stock and having a first density, an upper energy absorber disposed above the armrest and having a second density higher than the first density, and a lower energy absorber disposed below the armrest and having a third density higher than the first density.
1. A door trim panel, comprising:
a cover stock;
an armrest coupled to the cover stock and having a first density;
an upper energy absorber disposed above the armrest and having a second density higher than the first density; and
a lower energy absorber disposed below the armrest and having a third density higher than the first density,
wherein the armrest, upper energy absorber and lower energy absorber are formed from a polyolefin bead foam.
2. The door trim panel of claim 1 , wherein the second and third densities are substantially equal.
3. The door trim panel of claim 1 , wherein the cover stock is at least one of a textile, a polyvinyl chloride (PVC), and a thermoplastic olefin (TPO), each with a polypropylene foam backing.
4. A vehicle, comprising:
a body including a door; and
a door trim panel, the door trim panel including a cover stock, an armrest coupled to the cover stock and having a first density, an upper energy absorber disposed above the armrest and having a second density higher than the first density, and a lower energy absorber disposed below the armrest and having a third density higher than the first density,
wherein the armrest, upper energy absorber and lower energy absorber are formed from a polyolefin bead foam.
5. The vehicle of claim 4 , wherein the second and third densities are substantially equal.
6. The vehicle of claim 4 , wherein the cover stock is at least one of a textile, a polyvinyl chloride (PVC), and a thermoplastic olefin (TPO), each with a polypropylene foam backing.
7. A door trim panel, comprising:
a cover stock;
an armrest coupled to the cover stock and having a first density;
an upper energy absorber disposed above the armrest and having a second density higher than the first density; and
a lower energy absorber disposed below the armrest and having a third density higher than the first density and less than the second density,
wherein the armrest, upper energy absorber and lower energy absorber are formed from a polyolefin bead foam.
8. The door trim panel of claim 7 , wherein the cover stock is at least one of a textile, a polyvinyl chloride (PVC), and a thermoplastic olefin (TPO), each with a polypropylene foam backing.
9. The door trim panel of claim 7 , wherein the second density is between approximately 45 and 55 g/l and the third density is between approximately 40 and 50 g/l.
10. The vehicle of claim 4 , wherein the third density is less than the second density.
11. The vehicle of claim 10 , wherein the second density is between approximately 45 and 55 g/l and the third density is between approximately 40 and 50 g/l.
