Patent number: 6786550Abstract: A reclining device including a recess formed as a low-rigidity portion in a lateral portion of each of slide pawls which faces a lateral wall surface of a guide groove of a stationary disc (the lateral wall surface of a bearing wall portion). The stationary disc holds the slide pawls. If an enormous circumferential turning force is applied to the slide pawls from a ratchet, the recess functions as a point upon which a pawl body of each of the slide pawls is deflected in the direction in which the turning force is applied. As a result, the pawl body quickly sinks into the lateral wall surface of the bearing wall portion. Thus, the slide pawls are prevented from moving away from the ratchet.Type: GrantFiled: January 22, 2002Date of Patent: September 7, 2004Assignee: Araco Kabushiki KaishaInventor: Hideki Uramichi

Patent number: 6758525Abstract: It is possible to set a free zone and use a greater number of pawls in a reclining device having a plurality of pawls even if an angular range where a certain pawl is out of mesh with a ratchet and an angular range where pawls adjacent to that pawl are in mesh with the ratchet overlap with each other in a plan view, by bringing the other pawls out of mesh through an operation of bringing one specific pawl out of mesh. An unlock plate holds at least one pawl in retreat from the ratchet while a stationary disc holding the pawls and a movable disc having the ratchet form a relative rotational angle within a predetermined range. By holding the other pawls out of mesh through retreat of the pawl from the ratchet, an angular range for the operation of bringing one of the pawls out of mesh with the ratchet by means of the unlock plate, and an angular range for the operation where the adjacent pawls are brought into mesh with the ratchet are so set as to overlap with each other in a plan view.Type: GrantFiled: October 12, 2001Date of Patent: July 6, 2004Assignee: Araco Kabushiki KaishaInventor: Hideki Uramichi

Patent number: 6729172Abstract: Methods for manufacturing a press formed article (22) may include half die cutting a substantially flat material (1, 10) by press forming, thereby forming a first processed material (10′) having a first intermediate press formed article (16) defined therein. The half die cutting step is preferably performed while simultaneously compressing the central portion of the material in order to induce outward plastic flow within the first intermediate press formed article. These methods optionally may include pressing the first intermediate press formed article back into the first processed material, thereby forming a second processed material (10″) having a second intermediate press formed article (20), and separating the second intermediate press formed article from the second processed material, thereby forming a final processed material (10′″) and an unfinished press formed article (22′).Type: GrantFiled: October 8, 2002Date of Patent: May 4, 2004Assignee: Araco Kabushiki KaishaInventor: Jiro Aizaki

Patent number: 6722738Abstract: A reclining device has leg portions formed in opposed end portions of each of slide pawls. Basically, a rotating cam bears the slide pawl at a middle bearing portion formed in a middle portion between the leg portions. Furthermore, the rotating cam bears the slide pawl also at the leg portions. Such a three-point supporting structure prevents the middle portion of a slide pawl body from deflecting radially inwardly even in the event of application of a turning force from an annular ratchet. Thus, the slide pawls are stably maintained in mesh with the ratchet.Type: GrantFiled: January 14, 2002Date of Patent: April 20, 2004Assignee: Araco Kabushiki KaishaInventor: Hideki Uramichi

Patent number: 6645658Abstract: A separator of this invention is so constructed that a plurality of protrusions are implanted in a substrate which forms a reactive chamber of a fuel cell. The substrate has a multiple layered structure in which a single side or both sides of a mesh foundation are covered with resin layer and contains through holes at positions corresponding to each of the protrusions. Each of the protrusions is formed by allowing black lead ink applied on the single side or both sides of the substrate to invade each through hole. Consequently, the substrate can be formed to be super thin, lightweight and the respective protrusions can be easily formed at low cost.Type: GrantFiled: November 26, 2001Date of Patent: November 11, 2003Assignee: Araco Kabushiki KaishaInventor: Eiichiro Morozumi

Publication number: 20030178879Abstract: Seat reclining mechanisms for a vehicle seat may include a first housing (10) having a guide groove (20) that has first and second guide surfaces (24, 25), a second housing (12) having a toothed portion (13), and a pawl (16) slidably received in the guide groove. The pawl has first and second side surfaces (16b, 16c) that respectively correspond to the first and second guide surfaces of the guide groove. The pawl engages the toothed portion (13) of the second housing by sliding from its non-engaging position (C) to its engaging position (A) along the guide groove, thereby preventing the second housing from rotating relative to the first housing. The first side surface of the pawl and the first guide surface of the guide groove are arranged and constructed such that a clearance defined therebetween is changed so as to have an optimal width (S) when the pawl (16) is shifted from the non-engaging position (C) to the engaging position (A).Type: ApplicationFiled: March 10, 2003Publication date: September 25, 2003Applicant: Araco Kabushiki KaishaInventor: Hideki Uramichi
