Abstract
Abstract A stereophonic speaker headrest for motor vehicles includes a rigid interior shell and a padded cover. The rigid interior shell is generally hollow with a pair of opposed side wing members having speaker attachment structure therein for holding a speaker in each wing. The hollow portion of the rigid interior shell adjacent the speaker attachment structure forms an acoustic chamber. The padded cover provides substantial padding over the front and rear surfaces of the rigid interior shell, including the area in front of the speakers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
A stereo speaker headrest for a vehicle comprising a rigid interior shell having a pair of side wing members, each having a speaker opening, and a substantially arcuate central front surface, speaker attachment means for holding a pair of speakers such that each speaker is adjacent a different one of said speaker openings and such that the speakers are displaced laterally from one another, each wing member containing a speaker attachment means, an acoustical chamber defined by the walls of each wing member, a padded cover for substantially covering at least the front and rear surfaces of said rigid interior shell, and attachment means for attaching said headrest to a vehicle seat.
Claim 2
Dependent Claim
112 words
A stereo speaker headrest for a vehicle comprising a rigid interior shell having a pair of side wing members, each having a speaker opening, and a substantially arcuate central front surface, speaker attachment means for holding a pair of speakers such that each speaker is adjacent a different one of said speaker openings and such that the speakers are displaced laterally from one another, each wing member containing a speaker attachment means, an acoustical chamber defined by the walls of each wing member, a padded cover for substantially covering at least the front and rear surfaces of said rigid interior shell, and attachment means for attaching said headrest to a vehicle seat.
Claim 3
Dependent Claim
29 words
The headrest of claim 1 wherein said interior shell has a substantially arcuate rear surface, said rear surface having a substantially larger radius of curvature than said front surface.
Claim 4
Dependent Claim
