Description

本発明は乗用車や商用車、トラックやバス等の車両におけるシートの構造に関する。   The present invention relates to a seat structure in a vehicle such as a passenger car, a commercial vehicle, a truck or a bus.

車両のシート構造としては例えば特許文献１に開示されているように、シート（特許文献１の図２中の１６，１８）を、着座可能な使用姿勢で車体前後方向に位置調節自在に構成し（特許文献１の図２中の１６，１８の状態参照）、シートを使用姿勢及び使用姿勢から離れた非使用姿勢（特許文献１の図２中の１６，１８の跳ね上げられた状態参照）に亘って移動自在に構成したものがある。   As a vehicle seat structure, for example, as disclosed in Patent Document 1, a seat (16, 18 in FIG. 2 of Patent Document 1) is configured to be adjustable in the longitudinal direction of the vehicle body in a seating use posture. (Refer to states 16 and 18 in FIG. 2 of Patent Document 1), non-use posture that separates the seat from the use posture and the use posture (refer to the state of jumping 16 and 18 in FIG. 2 of Patent Document 1) There are some which are configured so as to be freely movable.

特許文献１の構造によると、車体固定部側（特許文献１の図３及び図４中の６８）に係止部（特許文献１の図３及び図４中の３８）が備えられ、シート側にロック機構（特許文献１の図３及び図４中の２０）が備えられている。これにより、シートを使用姿勢に設定した状態で、係止部を保持する保持状態にロック機構を操作することにより、シートを使用姿勢に保持することができるのであり、係止部の保持を解除する解除状態にロック機構を操作することにより、シートを非使用姿勢に設定することができる。   According to the structure of Patent Literature 1, a locking portion (38 in FIGS. 3 and 4 of Patent Literature 1) is provided on the vehicle body fixing portion side (68 in FIGS. 3 and 4 of Patent Literature 1), and the seat side Is provided with a locking mechanism (20 in FIGS. 3 and 4 of Patent Document 1). As a result, the seat can be held in the use posture by operating the lock mechanism in the holding state that holds the locking portion while the seat is set to the use posture, and the holding of the locking portion is released. The seat can be set to a non-use posture by operating the lock mechanism in the released state.

特許文献１の構造によると、ロック機構の保持及び解除状態への操作に連動して揺動するリンク（特許文献１の図３及び図４中の５２）が備えられており、シートを使用姿勢に設定した状態で車体前後方向の所定位置に操作すると、リンクの下方に回動保障孔（特許文献１の図３及び図４中の６６（細長いスリット状））が位置し、シートを使用姿勢に設定した状態で車体前後方向の所定位置以外の位置に操作すると、リンクの下方から回動保障孔が外れるように構成されている。   According to the structure of Patent Document 1, a link (52 in FIGS. 3 and 4 of Patent Document 1) that swings in conjunction with the operation of holding and releasing the lock mechanism is provided, and the seat is used. When the vehicle is operated to a predetermined position in the longitudinal direction of the vehicle body in the set state, a rotation guarantee hole (66 (elongated slit shape) in FIGS. 3 and 4 of Patent Document 1) is positioned below the link, and the seat is used. When the position is set to, and the operation is made to a position other than a predetermined position in the longitudinal direction of the vehicle body, the rotation ensuring hole is removed from the lower side of the link.

これにより、特許文献１の構造によると、シートを使用姿勢に設定した状態で車体前後方向の所定位置に操作した状態において、ロック機構の解除状態への操作に伴ってリンクが回動保障孔に入り込み（特許文献１の図３の状態参照）、ロック機構の解除状態への操作が行える。逆にシートを使用姿勢に設定した状態で車体前後方向の所定位置以外の位置に操作した状態において、ロック機構の解除状態への操作に伴ってリンクが回動保障孔に入り込むことができず（特許文献１の図４の状態参照）、ロック機構の解除状態への操作を行うことができない。   Thereby, according to the structure of patent document 1, in the state which operated the seat to the predetermined position of the vehicle body front-back direction in the state which set the use attitude | position, a link becomes a rotation guarantee hole with operation to the release state of a lock mechanism. It can enter (see the state of FIG. 3 of Patent Document 1) and operate the lock mechanism to the released state. Conversely, in a state where the seat is set to the use posture and operated to a position other than a predetermined position in the longitudinal direction of the vehicle body, the link cannot enter the rotation guarantee hole in accordance with the operation to the unlocking state of the lock mechanism ( The state of FIG. 4 of Patent Document 1) cannot be operated to the unlocked state of the lock mechanism.

特許第３４４５１６８号（図２，３，４）Japanese Patent No. 3445168 (FIGS. 2, 3 and 4)

特許文献１の構造によると、シートを使用姿勢に設定した状態で車体前後方向の所定位置に操作して、ロック機構を解除状態に操作する場合、ロック機構を解除状態に操作するのに伴ってリンクを揺動操作しなければならず、ロック機構の解除状態への操作が重いものになると考えられる。これにより、特許文献１の構造によると、ロック機構の解除状態への操作を軽いものにすると言う面で改善の余地がある。   According to the structure of Patent Document 1, when the lock mechanism is operated to the release state by operating the seat in the front-rear direction with the seat set to the use posture, the lock mechanism is operated to the release state. It is considered that the link must be swung, and the operation to release the lock mechanism becomes heavy. Thereby, according to the structure of patent document 1, there exists room for improvement in the aspect of lightening the operation to the cancellation | release state of a lock mechanism.

特許文献１の構造によると、シートを使用姿勢に設定した状態で車体前後方向の所定位置に操作した場合、リンクの下方に回動保障孔が位置することによって（リンクが回動保障孔に入り込み可能な状態になることによって）、ロック機構の解除状態への操作を行うことができる。
これにより、特許文献１の構造によると、シートを使用姿勢に設定した状態で車体前後方向の所定位置に操作した場合、機械的な誤差や組立誤差等によりリンクの下方に回動保障孔が精度良く位置していないと、リンクが回動保障孔に入り込めない状態になることがあり、シートを使用姿勢に設定した状態で車体前後方向の所定位置に操作しても、ロック機構の解除状態への操作を行うことができない（リンクが回動保障孔に入り込むことができない）ことが考えられる。 According to the structure of Patent Literature 1, when the seat is operated to a predetermined position in the vehicle longitudinal direction with the seat set to the use posture, the rotation guarantee hole is positioned below the link (the link enters the rotation guarantee hole). When it is possible, the lock mechanism can be operated to the unlocked state.
As a result, according to the structure of Patent Document 1, when the seat is operated in a predetermined position in the longitudinal direction of the vehicle body with the seat set in the use posture, the rotation guarantee hole is accurate under the link due to mechanical error or assembly error. If it is not positioned properly, the link may not be able to enter the rotation guarantee hole, and the lock mechanism is released even if the seat is set to the use posture and operated to a predetermined position in the vehicle longitudinal direction. It is conceivable that the operation cannot be performed (the link cannot enter the rotation ensuring hole).

本発明は車両のシート構造において、シートを着座可能な使用姿勢で車体前後方向に位置調節自在に構成し、シートを使用姿勢及び使用姿勢から離れた非使用姿勢に亘って移動自在に構成した場合、ロック機構の解除状態への操作が軽く行えるように構成することを目的としており、ロック機構の解除状態への操作が確実に行えるように構成することを目的としている。   The present invention is a vehicle seat structure in which the seat can be seated in a use posture that can be adjusted in the longitudinal direction of the vehicle body, and the seat can be moved in a use posture and a non-use posture away from the use posture. It is intended to be configured so that the operation to the unlocked state of the lock mechanism can be performed lightly, and to be configured so that the operation to the released state of the lock mechanism can be performed reliably.
