|20120326480||TILTABLE HEADREST DEVICE - A tiltable headrest device is provided to suppress the occurrence of abnormal noise during rotation, to reduce the number of components and to improve appearance quality. Guide portions (||12-27-2012|
|20120168246||SOUNDPROOFING COVER AND METHOD OF MANUFACTURING SAME - A soundproofing cover that has a sufficiently high soundproofing performance and that allows another member to be reliably attached to the soundproofing cover with a screw-fastening structure is provided. The soundproofing cover includes a cover body, a sound absorbing layer made of a urethane foam and formed integrally with the back surface of the cover body, and a nut member having a threaded hole that opens at both sides of the nut member in an axial direction. The nut member is embedded in the cover body in a manner such that an opening of the threaded hole in the nut member at a first end in the axial direction opens at a front surface of the cover body and an opening of the threaded hole at a second end in the axial direction is blocked by a blocking portion that is formed integrally with the cover body.||07-05-2012|
|20120133189||ARMREST DEVICE - An arm-rest device is constituted by including the following: an armrest body to be installed to a seat rotatably upward/downward; a ratchet mechanism including stationary-side first ratchet teeth, and movable-side second ratchet teeth rotating integrally with the armrest body; coiled springs for urging those in such a direction that they press one another; releasing cam units for releasing the ratchet mechanism from the meshing; elastic claws and a flanged portion for retaining that release; cut-offs for returning the ratchet mechanism to the meshing. And, the armrest body is made of resin, thereby integrally molding the second ratchet teeth at the time of its molding. It thus becomes an armrest device that is lightweight as a whole, whose assembly can also be done with less man-hour requirements, whose feeling of use is also satisfactory, and which is inexpensive and small in size.||05-31-2012|
|20100283307||HEAD REST APPARATUS - In the head rest apparatus, a core member is separately formed from a metal plate and a metal stay, wherein a fixing member is integrally formed on a first divided body of the core member and the fixing member mechanically engages the flat plate portion of the metal plate with the first divided body and fixes the flat plate portion to the first divided body. The flat plate position is tightly fixed to the first divided body. Since the stress can be absorbed only by the first divided body, generation of abnormal noise can be prevented without using any damper member and in addition, rattling in operation can be prevented as well.||11-11-2010|
