Abstract
Description
- The present invention relates to a headrest device having a headrest frame body and a stay, which is used in an automobile seat, and more particularly to a headrest device of which the headrest frame body covers a pair of leg member portions of the stay.
- As disclosed in Japanese Patent Laid-open Publication No. 382/1997 or Japanese Utility Model Laid-open Publication No. 113653/1986, for example, a headrest device used in an automobile seat includes, an inverse U-shaped stay having opposing leg member portions which are held by a seat back frame of a vehicle and a connecting portion which connects the leg member portions, and a headrest frame body which supports a headrest pad made of foaming resin. The headrest frame body is extended to a position above the connecting portion of the stay. The connecting portion and the headrest frame body are connected by using brackets or by way of bushings such that a portion of the headrest frame body is curled on the connecting portion.
- In such a prior art including means which connects the headrest frame body to the connecting portion of the stay using the brackets and means which connects a portion of the headrest frame body to the connecting portion of the stay by way of the bushing, the center of the headrest frame body is positioned above the connecting portion of the stay. Accordingly, when a load is applied to the headrest device, a force acting on a joint portion between the connecting portion of the stay and the headrest frame body becomes large and hence, it becomes necessary for the joint portion to have a sufficiently large connecting force (fastening force) . However, this increases a frictional force and hence, a manipulation force for tilting the headrest is also increased.
- In addition, in forming the headrest pad made of foaming resin on the headrest frame body by an integral molding process, it is necessary to prepare a separate member to protect the brackets or the curled portion from the wraparound of the foaming resin thus making the foaming operation difficult.
- On the other hand, assuming that the headrest frame body of the prior art is arranged below the connecting portion of the stay, the leg member portions of the stay become an exposed state to the headrest frame body. Accordingly, the rotational movement of the headrest in the back and forth direction becomes difficult due to the integrated foam molding of the headrest pad.
- Accordingly, it is an object of the present invention to provide a headrest device which can overcome such drawbacks of the prior art.
- To solve the above-mentioned drawbacks of the prior art, according to the present invention, as a basic structure, a headrest frame body adopts an overlapped structure made of two sheets of pressed members or a structure made of a single sheet of plate-like pressed member by a press-molded process, wherein the press-molded member cover leg member portions of a stay and a restricting portion which enables the tilting or the movement of the headrest in the back and forth direction is provided.
- With the provision of such basic constitutional conception, the tilting of the headrest in the back and forth direction becomes easy and there is no possibility that the tilting of the headrest which has an integral structure made of a headrest pad and a headrest frame body by a foam molding is hampered by the headrest pad.
- To be more specific, the present invention provides a headrest device including an inverse U-shaped stay having opposing leg member portions held by a seat back frame of a vehicle and a connecting portion which connects the leg member portions, and a headrest frame body which is supported on the stay such that the headrest frame body is rotatable in the back and forth direction about the connecting portion of the stay, wherein the headrest frame body is comprised of a pair of opposing plate bodies, each plate body comprises a support portion of an approximately semicircular cross section which has a portion coming into contact with the connecting portion of the stay and restricting portions of an approximately U-shaped cross section which cover the leg member portions of the stay and restrict the rotation of the headrest frame body about the connecting portion of the stay, and both plate bodies have a relationship where both plates have support portions and restricting portions thereof opposed and fixedly secured to each other.
- FIG. 1 is a perspective view with a part cut away of a headrest device of an embodiment of the present invention.
- FIG. 2 is a side view of the headrest device of the embodiment shown in FIG. 1 in the assembled state.
- FIG. 3 is a partial cross-sectional view showing a bead portion.
- FIG. 4 is a cross-sectional view of a friction holding portion defined between a stay and a headrest frame body.
- FIG. 5 is a cross-sectional view showing a pin caulking.
- FIG. 6 is a cross-sectional view showing a burring caulking.
- FIG. 7 is a bottom view showing an inner space of a restricting portion.
- FIG. 8 is a partial perspective view showing another embodiment of the present invention.
- An embodiment of the present invention is explained in more detail hereinafter in conjunction with FIG. 1.
- A headrest device1 is comprised of an inverted
U-shaped stay 2 and a pair ofplate bodies stay 2 is constituted by opposingleg member portions 4 which are held by a seat back frame of a vehicle not shown in the drawing and a connectingportion 5 which connects bothleg member portions 4. Thestay 2 is made of a pipe-like or solid rod having a circular cross section. - Each
plate body 3 is formed by pressing a metal sheet and is comprised of asupport portion 6 which has an approximately semicircular cross section and covers the connectingportion 5 of thestay 2 and restrictingportions leg member portions 4 of thestay 2. Theplate body 3 has a bead portion 8 (see FIG. 3) designated by the laws and regulations. Aplanar portion 9 is formed between both restrictingportions - A plurality of protruding
portions 10 which bulge inwardly are formed on an inner peripheral surface of thesupport portion 6. Theseprotruding portions 10 are brought into friction contact with an outer peripheral surface of the connectingportion 5 of thestay 2 thus providing a frictional movement of the headrest (see FIG. 4). -
Flange portions 11 which are directed inwardly are formed on free end peripheries of the restrictingportions flange portions 11 into contact with theleg member portions 4 of thestay 2, the tilting angle of theplate body 3 to thestay 2 is regulated. -
Respective plate bodies plate bodies plates bodies caulking using pins 12 as shown in FIG. 5 or by formingburring 13 on oneplaner portion 9 and performing a burring caulking through ahole 14 formed on theother planer portion 9 as shown in FIG. 6. The coupledplate bodies planar portion 9 and the caulking is performed on a center line of theplanar portion 9 disposed between thebead portion 8 and thesupport portion 6. - Besides caulking, portions of
respective plate bodies - The movement of the headrest frame body constituted by the
plate bodies - The relative movement between the headrest frame body constituted by the
plate bodies stay 2 is restricted by bringing theflange portions 11 into contact with theleg member portions 4 of thestay 2. Further, the headrest frame body constituted by theplate bodies support portions 6 of theplate bodies portion 5 of thestay 2. - Around the headrest frame body constituted by the
plate bodies plate bodies flange portions 11 can prevent the wraparound of the foaming resin into the inside of the restrictingportions 7 or can prevent the wraparound of the foaming resin between both opposingplanar portions 9 thereby the integrated foam molding of the headrest can be facilitated. - The inner wall surface which defines a
space portion 16 of the restrictingportion 7 may have acorrugated shape 15 as shown in FIG. 7. Thecorrugated shape 15 is formed by contiguously connecting arcuate surfaces having a diameter corresponding to a diameter of theleg member portion 4 of thestay 2. By seating theleg member portion 4 of thestay 2 on respective arcuate surfaces, the tilting position of the headrest frame body constituted by theplate bodies stay 2 can be surely held. When it is necessary to change the relative position of the headrest frame body constituted by theplate bodies stay 2, the headrest frame body constituted by theplate bodies leg member portion 4 of thestay 2 gets over a small ridge formed between contiguous arcuate surfaces. - Besides such a provision, an insert having the
corrugated form 15 may be prepared as a separate member and may be inserted into thespace portion 16 of the restrictingportion 7. - In an embodiment shown in FIG. 8, a headrest frame body is produced by forming a pair of
frame portions 20 by molding a sheet of metal plate with a press. A pair offrame portions 20 have the equal shape andrespective frame portions 20 are arranged in the left-and-right (or front-and-rear) symmetry. - Each
frame portion 20 which constitutes the headrest frame body includes anupper groove portion 21,side groove portions 22 and alower groove portion 23 at a side peripheral portion thereof. By coupling these twoframe portions 20 and fixedly securingflat planer portions 24 of theframe portions 20 by a spot welding or the like, the headrest frame body is formed. - The
upper groove portion 21 has a semicircular cross section to receive a connectingportion 5 of aninverse U-shaped stay 2.Cutout grooves 25 are formed in theupper groove portion 21 at two portions, preferably, at left and right portions thereof and theupper groove portion 21 extending between thecutout grooves 25 are brought into friction contact with the connectingportion 5 of thestay 2 so as to apply resistance to the tilting of the headrest frame body constituted by theframe portions portion 5. Here, thecutout grooves 25 contributes to the adjustment of the friction force between thestay 2 and the connectingportion 5. - The
side groove portions 22 have a shape for receiving leg member portions, that is,leg portions 4 of thestay 2. Theside groove portions 22 preferably increases the depth of the groove as theside groove portions 22 move in the downward direction such that theside groove portions 22 have a triangular shape when viewed from both sides thereof. - The
lower groove portion 23 has a shape suitable for ensuring the rigidity of theframe bodies opening portions 26 for allowing theleg portions 4 of thestay 2 to pass therethrough at a lower surface portion thereof. Theseopening portions 26 restrict the tilting of the headrest frame body to thestay 2. - The
