本考案は車両用座席に関し、特にヘッドレストをシート
バックに一体的に形成したものである。[Detailed Description of the Invention] The present invention relates to a vehicle seat, and particularly to one in which a headrest is integrally formed with a seat back.
従来、車両用座席においてシートバックに一体に形成す
るヘッドレストはバックフレームの上辺部にヘッドレス
トパネルを接合して形成していたが、バックフレームの
上辺部は偏平であり、この偏平な上辺部にヘッドレスト
パネルの下縁を横方向に直線状に接合するだけであるた
め、その上下方向の接合巾は極めて狭く、パネル面に衝
撃が加わると接合部に曲げ力が作用し、その接合部が曲
げ縁となって折曲変形したり、また接合部が破損剥離し
、特に後方からの衝撃即ち、後部座席の着座者が衝突し
た場合等にヘッドレスト部が変形し易い欠点があった。Conventionally, the headrest that is integrally formed with the seat back of a vehicle seat has been formed by joining a headrest panel to the upper side of the back frame, but the upper side of the back frame is flat, and the headrest is attached to this flat upper side. Since the lower edge of the panel is only joined horizontally in a straight line, the width of the joint in the vertical direction is extremely narrow, and when an impact is applied to the panel surface, bending force acts on the joint, causing the joint to bend. This has the disadvantage that the headrest part is easily deformed, such as when the headrest part is bent and deformed, or the joint part is damaged or peeled off, and the headrest part is easily deformed, especially when there is an impact from the rear, that is, when a passenger sitting in the rear seat collides with the headrest.
そこで本考案は従来の欠点を解消するもので、ヘッドレ
ストパネルのバックフレームに対する接合巾を増大し、
接合保持力を高めてヘッドレストをシートバックに対し
て強度的にも一体化されるようにしたものである。Therefore, the present invention solves the conventional drawbacks by increasing the joint width of the headrest panel to the back frame.
The headrest is strengthened and integrated with the seatback by increasing the joint retention force.
以下図面について本考案の一実施例を説明する。An embodiment of the present invention will be described below with reference to the drawings.
図において1は本考案を適用する車両用座席の全体を示
し、2はシートクッション、3はシートバックでこのシ
ートバック3に本考案によるヘッドレスト4が備えられ
ている。In the figure, 1 shows the entire vehicle seat to which the present invention is applied, 2 is a seat cushion, 3 is a seat back, and this seat back 3 is equipped with a headrest 4 according to the present invention.
即ちシートバック3のバックフレーム5の上辺部5aを
山形伏に形成し、この山形状上辺部5aの中央部分に、
ヘッドレストパネル6を接合する。That is, the upper side 5a of the back frame 5 of the seat back 3 is formed into a chevron shape, and in the center part of this chevron-shaped upper side 5a,
The headrest panel 6 is joined.
このヘッドレストパネル6の中央部分にハハックフレー

a、7bが形成されて下縁部7cはヘッドレストパネル
6の下縁両側部6a、6bとフレーム上辺部5aの直径
と略同じ間隔で前後に離隔された状態で位置される。At the center of the headrest panel 6, a bead 7 with a depth approximately equal to the diameter of the chevron-shaped upper side 5a of the HAC frame 5 is formed by expanding forward. Concave portion 7 along the upper half of the portion 5a
a, 7b are formed, and the lower edge portion 7c is spaced back and forth at approximately the same distance as the diameter of the lower edge side portions 6a, 6b of the headrest panel 6 and the frame upper side portion 5a.
このヘッドレストパネル6の下縁部をバックフレーム5
の山形上辺部5aの中央部において、両側下縁部6a、
6bを後面側に、ビート下縁部7cを前面側に位置させ
て挟挿し、各下縁部6at6b及び7cを夫々フレーム
上辺部5aに対して点溶接により接合する。The lower edge of this headrest panel 6 is attached to the back frame 5.
In the center of the chevron-shaped upper side 5a, both lower edges 6a,
6b is placed on the rear side and the bead lower edge 7c is placed on the front side, and the lower edges 6at6b and 7c are joined to the frame upper side 5a by spot welding.
このようにしてヘッドレストパネル6をバックフレーム
5に接合すると、バックフレーム5の上辺部5aに対す

溶接点W1とW2との上下方向の間隔中aが大きく、ま
た各溶接点W1.W2はフレーム上辺部5aの山形に沿
って点在することになるのでバックフレーム5に対する
ヘッドレストパネル6の接合部は拡大される。When the headrest panel 6 is joined to the back frame 5 in this way, the vertical distance between the welding points W1 and W2 between the panel's lower edges 6a, 6b and the bead lower edge 7c with respect to the upper side 5a of the back frame 5. The center a is large, and each welding point W1. Since the W2 are scattered along the mountain shape of the upper frame portion 5a, the joint portion of the headrest panel 6 to the back frame 5 is enlarged.
なお、図中8はバックフレーム5に架張した8字ばねで
ある。In addition, 8 in the figure is a figure 8 spring stretched over the back frame 5.
本例においてはバックフレーム5を管材により閉断面状

用いてもよい。In this example, the back frame 5 is made of tubular material and has a closed cross-sectional shape, but there is also a back frame that is formed in an inverted U shape and whose open parts are connected by connecting rods, or a back frame that is formed of a steel plate. It goes without saying that the headrest panel 6 can be joined to the above-mentioned parts by the above-described structure, and the welding is not limited to spot welding, and other bath welding methods may be used.
以上のように本考案によればバックフレームの上辺部を

が簡単で製作も容易である等の効果を有する。As described above, according to the present invention, the upper side of the back frame is shaped like a mountain, and the lower edge of the headrest panel, which is divided into multiple parts, is inserted into the mountain-shaped upper side from the front and rear sides and joined. The vertical distance between these joints is expanded to improve the joint strength of the headrest panel to the back frame, and the headrest panel can withstand not only shocks from the front side but also shocks applied from the rear side, especially from diagonally above the rear side. The headrest is integrated with the seat back in terms of strength, can reliably protect the seated person, and has the advantage of being simple in structure and easy to manufacture.
